# 1 INTRO

iCalcreator is a PHP class package managing iCal files, supporting (non-)calendar systems and applications to process and communicate calendar information like events, agendas, tasks, reports, totos and journaling information.

The iCal standards are rfc5545/rfc5546 (rfc2445/rfc2446).

iCalcreator features create, parse, edit and select calendar and calendar components.

The iCalcreator package, based of a calendar / components classes and with support of function classes and helper functions, are calendar component property oriented. For iCalcreator 2.22 version (and later), PHP version >= 5.3 is required.

More iCalcreator supplementary, "howto" and coding support information will be found at kigkonsult.se iCalcreator implement examples and test pages. A strong recommendation is to have this document open in parallell when exploiting the link.

iCalcreator may support hiphop if the HDF AllDynamic option is enabled (the helper iCal2XML function is excluded).

## 1.1 Standards

#### iCal

The iCalendar format, iCal, as described in

rfc5545
  "Internet Calendaring and Scheduling Core Object Specification (iCalendar)"
rfc5546
  "iCalendar Transport-Independent Interoperability Protocol (iTIP)"
  Scheduling Events, BusyTime, To-dos and Journal Entries

. ..allows for the capture and exchange of information normally stored within a calendaring and scheduling application.

and

. ..is an exchange format between applications or systems.

rfc5545 and rfc5546 obsoletes, respectively, rfc2445 and rfc2446.

A short iCal description is found at Wikipedia. If You are not familiar with iCal, read this first! Knowledge of calendar protocol rfc5545/rfc5546 is to recommend.

Any references to rfc2445, below, corresponds to rfc5545.

#### xCal

iCalcreator also supports xCal (iCal xml) rfc6321, "xCal: The XML Format for iCalendar", to be downloaded from

rfc6321
  "xCal: The XML Format for iCalendar"

A short xCal description is found at Wikipedia.

The older xCal format, as defined in "http://www.ietf.org/internet-drafts/draft-ietf-calsch-many-xcal-01.txt" (but no longer found), still works in this version but will not be maintaned and will be removed in future versions.

## 1.3 Versioning

The release numbering convention used is major.minor(.micro / suffix).

Major
  Indicates a very large change in the core package. Rewrites or major milestones.
Minor
  Significant amount of feature addition/modification.
  odd number - development/experimental release
  even number - production release
Micro
  Primarily bug fix and maintenance number.
Suffix
  rc1 for first release candidate etc.

The release plan is based on yearly releases with exception of emergency releases.

## 1.4 Support

Use the kigkonsult.se standard support page exploring iCalcreator use and iCal issues.

Support and development is now focused on iCalcreator (Pro) 3.x versions, which, in turn, will affect future releases of iCalcreator 2.x.

Use the contact page for queries, improvement/development issues or professional support and development. Please note that paid support or consulting service has the highest priority.

## 1.6 Install

Unpack to any folder
- add this folder to your include-path
- or unpack to your application-(include)-folder

Add

require_once "[path/]iCalcreator-<version>/iCalcreator.php";

to your PHP-script. The iCalcreator invoke has changed since previous version! You may also need to set the default timezone.

Creating a new iCalcreator object instance/component instance, review config settings.

[index] [top]

## 1.7 Additional Descriptors

The following properties (as described in wikipedia:iCal) may be required when importing iCal files into some calendaring software (MS etc.):

on calendar level
  METHOD property (value PUBLISH etc.)
  X-WR-CALNAME x-property
  X-WR-CALDESC x-property
  X-WR-RELCALID x-property (Read more info about UUID.)
  X-WR-TIMEZONE x-property
on component level
  DTSTAMP property (in iCalcreator created automatically, if not set)
  UID property (in iCalcreator created automatically, if not set)
on component level in a vtimezone component
  X-LIC-LOCATION x-property

Example

A strong recommendation is also to set config unique_id, creating a new vcalendar/component instance, to ensure accurate setting of all components UID property, especially before parse. Also setting of config timezone ("TZID" and "X-WR-TIMEZONE" below) is to recommend.

<?php .. . $config = array( "unique_id" => "kigkonsult.se", "TZID" => "Europe/Stockholm" ); $vcalendar = new vcalendar( $config ); $vcalendar->setProperty( "method", "PUBLISH" ) $vcalendar->setProperty( "x-wr-calname", "Calendar Sample" ); $vcalendar->setProperty( "X-WR-CALDESC", "Calendar Description" ); $uuid = "3E26604A-50F4-4449-8B3E-E4F4932D05B5"; $vcalendar->setProperty( "X-WR-RELCALID", $uuid ); $vcalendar->setProperty( "X-WR-TIMEZONE", "Europe/Stockholm" ); .. .

## 1.8 Addendum

For iCalcreator usage, coding samples and tests, visit the public kigkonsult.se test resource.

Examples how to employ iCalcreator in software development
  dbiCal, an iCal file PHP database backend solution.
  The iCal file event editor
  tinycal, calendar-in-a-box.

There are free iCal/xCal icons (use as buttons on a web page?) to download here.

The PHP coding in this document or "coding samples" (above) are only for display of usage, recommendation is to use a coding standard, the following, incomplete, list is a good start;

  PHP Framework Interop Group Basic Coding Standard
  pear Coding standards

If not set, the DTSTAMP and UID properties are automatically created by iCalcreator
for vevent,vtodo, vjournal and vfreebusy components
when using iCalcreator object methods saveCalendar or returnCalendar
or when fetching DTSTAMP/UID property value with the component function getProperty.

# 3 Function list

## 3.1 iCalcreator object methods

### 3.1.1 Constructors

#### 3.1.1.1 vcalendar

Create a new VCALENDAR object.

Format

vcalendar::vcalendar( [ config ] )

config = array, review configuration options.

Basic example

<?php .. . $config = array( "unique_id" => "kigkonsult.se" ); $vcalendar = new vcalendar( $config ); ...

The calendar property PRODID and each component property UID are AUTOMATICALLY generated in iCalcreator, if not set manually, and based on the configuration unique_id.

Extended example

<?php .. . $tz = "Europe/Stockholm" $config = array( "unique_id" => "kigkonsult.se" "TZID" => $tz ); $vcalendar = new vcalendar( $config ); $vcalendar->setProperty( "X-WR-TIMEZONE", $tz ); .. . .. . // insert components or parse an iCal file (and edit components) .. . $xprops = array( "X-LIC-LOCATION" => $tz ); iCalUtilityFunctions::createTimezone( $vcalendar, $tz, $xprops ); .. .

The TZID config key and value (timezone) is supplied when setting DTSTART, DTEND, DUE or RECURRENCE-ID, if not set manually, a TZID auto completion.

Some calendar software may also require calendar property X-WR-TIMEZONE and vtimezone component with property X-LIC-LOCATION, review createTimezone, a function in iCalUtilityFunctions class.

Do NOT set directory/filename in vcalendar constructor, due to inability to detect error (FALSE) config return.

[index] [top] [up]

#### 3.1.1.2 vevent

Format 1

Create a new VEVENT object using an iCalcreator object component factory-method, returning a reference to the new component.

vcalendar::newComponent( "vevent" )

Example

<?php .. . $config = array( "unique_id" => "kigkonsult.se", "TZID" => "Europe/Stockholm" ); $vcalendar = new vcalendar( $config ); ... $vevent = & $vcalendar->newComponent( "vevent" ); $vevent->setProperty(... ...

Format 2

Create a new VEVENT object.

vevent::vevent( [ config ] )

Format 1

Selects EVENT / VTODO / VJOURNAL / VFREEBUSY components from the iCalcreator object instance on based on dates (notice date restriction), based on the initial DTSTART property along with the RRULE, RDATE, EXDATE and EXRULE properties in the component.

Requirement:

- The property DTSTART is required. If missing in a VTODO component, DUE is used.
- If not using local date, timezone in property DTSTART etc. MUST be PHP complient.

Limitations:

- The values "SECONDLY" / "MINUTELY" / "HOURLY" in the "FREQ" rule part are NOT supported.
- If using components with properties
  UID in combination with SEQUENCE and RECURRENCE-ID
  (i.e. altering an individual instance within the recurrence set),
  the RECURRENCE-ID parameter "RANGE" ("THISANDPRIOR" / "THISANDFUTURE") is NOT (yet) supported.
- only one reccurrence a day
- a RDATE reccurrence will overwrite any RRULE reccurrence, on an date (Ymd) basis
- no X-CURRENT-DTEND if no DTEND (DUE) is set (below)

Returns an array with components (events.. .) or FALSE is returned if no selected component exists.

Added X-properties in recurrent instances of a calendar component:

- "X-CURRENT-DTSTART", TEXT content, "Y-m-d [H:i:s [timezone]]" showing the current start date.
- "X-CURRENT-DTEND" alt. "X-CURRENT-DUE" (opt), TEXT content, "Y-m-d [H:i:s [timezone]]" showing the current end date.
- "X-RECURRENCE", the RRULE/RDATE recurrence pattarn number (none in the recurrence start), also after an RECURRENCE-ID change

format 2

Using this format, the iCalcreator object method selects components based on specific property value(-s).

Supported Descriptive Component Properties
  CATEGORIES
  LOCATION
  PRIORITY
  RESOURCES
  STATUS
  SUMMARY
Supported Relationship Component Properties
  ATTENDEE *1
  CONTACT
  ORGANIZER *1
  RELATED-TO
  URL
  UID

*1
  ATTENDEE and ORGANIZER search values must be prefixed by (upper case) protocol like "MAILTO:chair@ical.net".

For the property SUMMARY, if a search value (any case) exists within property value, a hit is found. For the other properties an exact (strict case) match is required. Multiple search properties may coexist.

To retrieve specific iCalcreator instance property values, searching ALL components, use getProperty (Format 2).

To get components based on property values, use getComponent (Format 5).

vcalendar::selectComponents( searchArray )

Outputs an array of matched (unique) components in UID order.

searchArray : (array) *( propertyName => propertyValue ) propertyName : (string) above (any case) propertyValue : (string) value / (array) ( *[ (string) value] )

Example

<?php .. . $config = array( "unique_id" => "kigkonsult.se", "directory" => "import", "filename" => "file.ics" ); $vcalendar = new vcalendar( $config ); $vcalendar->parse(); $searchArray = array( "PRIORITY" => array( 1, 2, 3, 4 )); $highPrioArr = $vcalendar->selectComponents( $searchArray ); // select all components with PRIORITY set to high (1-4) if( !empty( $highPrioArr )) { $highPrioCal = new vcalendar( array( "unique_id" => "kigkonsult.se" )); $highPrioCal->setProperty( "X-WR-CALDESC", "High priority events" ); foreach( $highPrioArr as $highPrioComponent ) $highPrioCal->setComponent( $highPrioComponent ); $highPrioCal->returnCalendar(); } exit;

#### 3.1.3.6 setComponent

Replace or update component in the iCalcreator object instance. Also add a calendar component to the iCalcreator object instance when calendar component is created with the procedural (non-factory) method, see example VEVENT, format 2.

A successful update returns TRUE.

format 1

Insert last in component chain.

vcalendar::setComponent( component ) addComponent( component ) // alias

component = (object) iCalcreator component instance

addComponent, may be removed in future versions.

format 2

Insert/replace component with order number (1st=1, 2nd=2.. .). If replace and orderNumber is not found, component is inserted last in chain.

vcalendar::setComponent( component, orderNumber )

component = (object) iCalcreator component instance int = (int) order numder

format 3

Replace component with component type and 1st alt. component order number. If orderNumber is not found, component is inserted last in chain.

vcalendar::setComponent( component, componentType [, componentSuborderNo])

component = (object) iCalcreator component instance componentType = (string) component type componentSuborderNo = (int) component Suborder Number

format 4

Replace component with UID. N.B UID is NOT set for ALARM / TIMEZONE components. If UID is not found, component is inserted last in chain.

vcalendar::setComponent( component, UID )

component = (object) iCalcreator component instance

Example

<?php .. . $config = array( "unique_id" => "kigkonsult.se", "filename" => "file.ics"); $vcalendar = new vcalendar( $config ); $vcalendar->parse(); $vevent = vcalendar->getComponent( 1 ); // fetch first EVENT $vevent->setProperty( "dtstart, 2006, 12, 24, 19, 30, 00 ); // update DTSTART property $vcalendar->setComponent( $vevent, 1 ); // replace first component .. .

### 3.1.4 iCalcreator calendar methods

#### 3.1.4.1 parse and merge

Parse iCal file(-s) or string/array calendar content into a single iCalcreator object instance (components, properties and parameters), including multiple vcalendars (within a single ICS file) parse, e.g. Oracle Calendar exports.

As long as php.ini directive "allow_url_fopen" is enabled, remote files, URLs; protocol "http" ("webcal"), are supported. A remote file, URL, must be prefixed by "http://" ("webcal://") and suffixed by a valid filename.! Recommendation is to download (cache) remote file before parsing, due to execution time and control.

If missing, component property UID is created when parsing. For that reason UNIQUE_ID might need to be set before parsing, Se examples below.

Notice date restriction!

If major parse error occurs (like file access error, invalid calendar file or calendar file without components), FALSE is returned.

Minor errors like non-standard line-endings, initial and trailing empty lines as well as files without proper end line(-s) (i.e. missing component end and/or "END:CALENDAR" iCal directives) are managed.

Non-standard iCal properties (except the X-properties) are ignored.

Format

vcalendar::parse( [ textToParse ] )

textToParse = (string) calendarContent ex. result from - file_get_contents( "filename") (array) calendarContent ex. result from - file( "filename", FILE_IGNORE_NEW_LINES )

parse example 1

<?php .. . $config = array( "unique_id" => "kigkonsult.se", "filename" => "file.ics" ); $vcalendar = new vcalendar( $config ); $vcalendar->parse(); .. .

parse example 2

<?php .. . $config = array( "unique_id" => "kigkonsult.se", "url" => "http://www.ical.net/calendars/calendar.ics" ); $vcalendar = new vcalendar( $config ); $vcalendar->parse(); .. .

parse example 3

<?php .. . $config = array( "unique_id" => "kigkonsult.se", "url" => "http://www.ical.net/calendars/calendar.ics" ); $vcalendar = new vcalendar( $config ); ... $str = array( "BEGIN:VCALENDAR", "PRODID:-//kigkonsult.se//NONSGML kigkonsult.se iCalcreator 2.22//", "VERSION:2.0", "BEGIN:VEVENT", "DTSTART:20101224T190000Z", "DTEND:20101224T200000Z", "DTSTAMP:20101020T103827Z", "UID:20101020T113827-1234GkdhFR@test.org", "DESCRIPTION:example", "END:VEVENT", "END:VCALENDAR"); $vcalendar->parse( $str ); ...

$filename = date( "YmdHis" ).".ics" .

NOTE, the method no longer stops PHP script (exit), returns TRUE on success!

Format

vcalendar::returnCalendar( [ utf8Encode [, gzip [, cdType ]]] )

utf8Encode = (bool) TRUE: utf8 encoded output, FALSE: (default) no encoding gzip = (bool) TRUE: gzip compressed output Header "Content-Length" only sent when gzip=TRUE FALSE: (default) no compressing cdType = (bool) TRUE: (default) Content-Disposition: attachment FALSE: Content-Disposition: inline

Example 1

#### 3.1.4.5 sort

Format 1

Sort created/parsed calendar components on the following (prioritized) keys:
1 - X-CURRENT-DTSTART - X-CURRENT-DTEND/X-CURRENT-DUE
(if created in iCalcreator object method selectComponents)
1 - DTSTART - DTEND alt. DURATION (VEVENT and VFREEBUSY components)
1 - DTSTART - DUE alt. DURATION (VTODO components)
1 - DTSTART (VJOURNAL components)
2 - CREATED / DTSTAMP
3 - UID
A date value, like "DTSTART;VALUE=DATE:20120717", are sorted before a datetime value.
VTIMEZONE component(-s) is always placed first (ordered by TZID). The STANDARD / DAYLIGHT sub-components are sorted (on asc. key DTSTART) when calling createCalendar (or returnCalender).
ALARM sub-components, if exists, are not sorted.

vcalendar::sort()

Example

<?php .. . $config = array( "unique_id" => "kigkonsult.se", "directory" => "import", "filename" => "file.ics" ); $vcalendar = new vcalendar( $config ); $vcalendar->parse(); $vcalendar->sort(); $vcalendar->returnCalendar(); exit;

Format 2

Sort created/parsed calendar components based on specific property values and ascending order. If a property is not set in component, an empty sort key is used (i.e. sorted first).

vcalendar::sort( sortArgument )

sortArgument: (string) "ATTENDEE" * / "CATEGORIES" * / "CONTACT" * / "DTSTAMP" / "LOCATION"" / "ORGANIZER" / "PRIORITY" / "RESOURCES" * / "STATUS" / "SUMMARY" / "URL" / "UID" **.

*) For a property where multiple occurrence may exist (ATTENDEE, CATEGORIES, CONTACT, RESOURCES) lowest (alphabetic) value is used as sort key.

**) For multiple components with the same UID, components with RECURRENCE-ID / SEQUENCE set are sorted first (on asc. values) and components without RECURRENCE-ID last.

Allow or reject empty calendar properties. Used in createCalendar, returnCalender or create<Property> methods, creating [RFC5545] formats.

Default TRUE (allow).

[index] [top] [up]

#### 3.1.5.6 Component information

Only to use with iCalcreator object method getConfig.

Get information about the iCalcreator object instance components. Returns array with basic information about all components (in array format) within the iCalcreator object instance.

Output = array ( *compinfo ) compinfo = array ( "ordno" => int ordno, // order number (1st=1, 2nd=2..) , "type" => string type // component type (vevent, vtodo.. . , "uid" => string uid // component UID (not for ALARM / TIMEZONE) , "props" => array( *[ propertyName => Property count ]) // for every set property , "sub" => array( *compinfo )) // if subcomponents exists, an array for each subcomponent

#### 3.1.5.7 Delimiter

Directory/filename delimiter.

Default PHP constant DIRECTORY_SEPARATOR. If used, must be set BEFORE filename!

[index] [top] [up]

#### 3.1.5.8 Directory

Local directory to store/read iCal files.

Default ".".

Directory must be set BEFORE filename and must exist and be writeable otherwise FALSE is returned. If set using an config array and together with Filename, Directory are set automatically first. When setting directory, the PHP realpath function is applied to speed up parse/saveCalendar methods. When setting Directory, any previously set URL is removed.

Example

<?php ... $dir = 'test'; if( FALSE === $vcalendar->setConfig( array( 'directory' => $dir ))) die( "Invalid directory $dir" ); ...

For temporary calendar files, you may set directory/filename using PHP functions sys_get_temp_dir() and tempnam().

Do NOT set directory/filename in vcalendar constructor, due to inability to detect error (FALSE) config return.

[index] [top] [up]

#### 3.1.5.9 Dirfile

Only available in iCalcreator object method getConfig, returning (string) directory, delimiter and filename.

[index] [top] [up]

#### 3.1.5.10 Fileinfo

Only available in iCalcreator object method getConfig, giving information in array format about directory, filename and filesize.

Example

<?php .. . $fileinfo = $vcalendar->getConfig( "fileinfo" ); .. .

output = array( <directory>, <filename>, <filesize> )

[index] [top] [up]

#### 3.1.5.11 Filename

iCal local file name, default created like (if not set):

$filename = date( "YmdHis" ).".ics";

$filename = date( "YmdHis" ).".xml"; // if format set to "xcal"

If not set, filename is created when requested, ex. in iCalcreator object methods saveCalendar or getConfig("filename").

Local filename must be set AFTER setting directory (and opt. delimiter)! Filename (and opt. directory) must be readable/writeable otherwise FALSE is returned.

Example

<?php ... $dir = 'test'; if( FALSE === $vcalendar->setConfig( array( "directory" => $dir ))) die( "Error when config directory $dir" ); $file = 'temp.ics'; if( FALSE === $vcalendar->setConfig( array( "filename" => $file ))) die( "Error when config filename $file" ); ...

For temporary calendar files, you may set directory/filename using PHP functions sys_get_temp_dir() and tempnam().

Do NOT set directory/filename in vcalendar constructor, due to inability to detect error (FALSE) config return.

[index] [top] [up]

#### 3.1.5.12 Filesize

Only when getting configuration (using iCalcreator object method getConfig).
Returns the size of the file in bytes, to be invoked
- after "saveCalendar()"
or
- after a "setConfig( "directory" / "filename" )" and before/after "parse()".
Getting the filesize for a remote file (URL) will always return zero.

[index] [top] [up]

#### 3.1.5.13 Format

Format for the iCalcreator object instance output, "iCal"/"xCal", any case.

"iCal" is default ([RFC5545]), "xCal" force xml formatted output, according to
"draft-ietf-calsch-many-xcal-01.txt" (now obsolete).

For converting to and from XML, according to rfc6321, "xCal: The XML Format for iCalendar",use functions
- iCal2XML converts an iCalcreator object instance to XML
- XML2iCal converts XML (string/file) to an iCalcreator object instance.

[index] [top] [up]

#### 3.1.5.14 Language

Language for the iCalcreator object instance and component TEXT value properties as defined in [RFC5646].

Default empty.

If NOT set in TEXT property parameters, language from component instance "setConfig( "language", ..)" method will be used, if set, otherwise language from calendar method "setConfig( "language", ..)" will be used, if set.

The calendar property PRODID is always recreated when setting (calendar) language (, note Unique_id, below).

[index] [top] [up]

#### 3.1.5.15 NewlineChar

Character(s) used for carriage return + line feed (CR+LF).

Default "\r\n" as defined in [RFC5545].

[index] [top] [up]

#### 3.1.5.16 setPropertyNames

Returns array of property names for all set properties in component. "X-PROP" will be used when X-properties are set.

[index] [top] [up]

#### 3.1.5.17 TZID

General timezone, will be used if no TZID parameter is supplied when setting DTSTART, DTEND, DUE or RECURRENCE-ID, a TZID auto completion.

Default empty.

Note, some calendar software may also require calendar property X-WR-TIMEZONE and vtimezone component property X-LIC-LOCATION (to be set manually, examine also the createTimezone function).

[index] [top] [up]

#### 3.1.5.18 Unique_id

"Unique_id" is used in calendar property PRODID and component property UID, both created automatically (, if not setting UID manually.

PRODID The identifier is RECOMMENDED to be the identical syntax to the [RFC 822] addr-spec. A good method to assure uniqueness is to put the domain name or a domain literal IP address of the host on which.. .

Default AUTOMATICALLY generated by using PHP function gethostbyname( $_SERVER["SERVER_NAME"] ) when running in a web server environment or "localhost" when using command line interface. Used when setting other (domain) name than server name.

The calendar property PRODID is always recreated when setting unique_id.

If missing, the component property UID is created at first use of iCalcreator object methods createCalendar, returnCalendar or saveCalendar

A strong recommendation is always to set unique_id, creating a new iCalcreator object or component instance, to ensure accurate creation of all components UID property, also before parse, in case of missing UID.

[index] [top] [up]

#### 3.1.5.19 URL

When reading remote files or resources with URL (using the parse() method), protocol "http" ("webcal") and "https" are supported.

When setting URL, the previously set Directory is removed.

A remote file is identified by the file suffix ".ics", otherwise the URL is classified as a resource. When setting URL to a remote iCal file, only directory need to be (re-)set, filename remains unchanged (i.e. 1. set URL, 2. parse, 3. set directory, 4. saveCalendar). The URL remote file file part can be retrieved by the vcalendar method getConfig( "filename" ). When using a resource, filename is unset (note filename, above).

Example

Parse of remote file, then local save in "depot" folder, using original filename

<?php .. . $config = array( "unique_id" => "kigkonsult.se", "url" => "http://www.iCal.net/depot/calendar.ics" ); $vcalendar = new vcalendar( $config ); $vcalendar->parse(); $vcalendar->sort(); .. . .. . $vcalendar->setConfig( "directory", "depot" ); $vcalendar->saveCalendar(); .. .

## 3.2 Calendar component property method list

All iCalcreator component object property methods for get/set data.
For property format in detail, see RFC2445 - Internet Calendaring and Scheduling Core Object Specification (iCalendar).

Notice: for properties and DATE-TIME with UTC time.

RFC2445: The date with UTC time, or absolute time, is identified by a LATIN CAPITAL LETTER Z suffix character (US-ASCII decimal 90), the UTC designator, appended to the time value. For example, the following represents January 19, 1998, at 0700 UTC:

DTSTART:19980119T070000Z

The TZID property parameter MUST NOT be applied to DATE-TIME properties whose time values are specified in UTC.

Notice: date limitation.
Due to a limitation in PHP date functions, e.g. mktime, strtotime, a date (e.g. while setting DTSTART property) before "January 1 1970 00:00:00 GMT" may force a PHP date function to generate an error or set date to "January 1 1970".

### 3.2.1 deleteProperty

Generic iCalcreator object instance delete property method,simplifying removal of calendar properties.
FALSE is returned if no property exists or when end-of-properties at consecutive function calls.

Format

calendarComponent::deleteProperty( [ PropName [, order ] )

propName = (string) case independent, [RFC5545] component property names, unknown/missing propName will be used as X-property. order = (int) if missing 1st/next occurrence, used with multiply (property) occurrences

Example

Remove all COMMENT properties in first event component.

<?php .. . $config = array( "unique_id" => "kigkonsult.se", "directory" => "import", "filename" => "file.ics" ); $vcalendar = new vcalendar( $config ); $vcalendar->parse(); $event = $vcalendar->getComponent( "vevent" ); while( $event->deleteProperty( "comment" )) continue; .. .

[index] [top] [up]

### 3.2.2 getProperty

Generic iCalcreator component get property method, simplifying fetch of properties.

FALSE is returned if no property exists or when end-of-properties at consecutive function calls.

Using the non-standard directive "GEOLOCATION", iCalcreator returns output supporting
ISO6709 "Standard representation of geographic point location by coordinates",
by combining the LOCATION and GEO property values (only if GEO is set).

Format

calendarComponent::getProperty( PropName [, order [, complete ]] )

### 3.2.3 parse

Parse iCal component property text from a string or an array. Each string/array row must be strict RFC5545 formatted, i.e. begin with a property name.

Complete ALARMs, all properties included, in array format and first array row as "BEGIN:VALARM", last as "END:VALARM" as well as TIMEZONE and standard/daylight subcomponents.

If major parse error occurs (like invalid calendar structure or no calendar components), FALSE is returned.

Minor errors like non-standard line-endings, initial and trailing empty lines as well as files without proper end line(-s) (i.e. missing component end iCal directives) are managed.

Except the X-properties, non-standard properties are ignored.

Format

calendarComponent::parse( propertyText )

propertyText = (string) [RFC5545] formatted property, (array) [RFC5545] formatted properties, property name must start string / rows(-s)

example

<?php .. . $e = & $vcalendar->newComponent( "vevent" ); $e->parse( "DTSTAMP:19970324T1200Z" ); $e->parse( "SEQUENCE:0" ); $e->parse( "ORGANIZER:MAILTO:jdoe@host1.com" ); $e->parse( array( "ATTENDEE;RSVP=TRUE:MAILTO:jsmith@host1.com", "ATTENDEE;RSVP=TRUE:MAILTO:jsmith@host2.com", "ATTENDEE;RSVP=TRUE:MAILTO:jsmith@host3.com", "ATTENDEE;RSVP=TRUE:MAILTO:jsmith@host4.com" )); $e->parse( "DTSTART:19970324T123000Z" ); $e->parse( "DTEND:19970324T210000Z" ); $e->parse( "CATEGORIES:MEETING,PROJECT" ); $e->parse( "CLASS:PUBLIC" ); $e->parse( "SUMMARY:Calendaring Interoperability Planning Meeting" ); $e->parse( "STATUS:DRAFT" ); $e->parse( "DESCRIPTION:Project xyz Review Meeting Minutes\\n " .

### 3.2.15 DTEND

This property specifies the date and time that a calendar component ends. The property is OPTIONAL and MUST NOT occur more than once in VFREEBUSY and VEVENT. In VEVENT, it only occurs if DURATION NOT occurs.

The default value type for DTEND is DATE-TIME, can be set to a DATE value type.

The value type of the "DTEND" or "DUE" properties MUST match the value type of "DTSTART" property as defined in [RFC5545])

Notice that an end date without a time is in effect midnight of the day before the date, so for timeless dates, use the date following the event date for it to be correct. For an "all-day event" and using timeless dates, the DTEND is equal DTSTART plus one day, example all-day event (2007-12-01)
DTSTART;VALUE=DATE:20071201
DTEND;VALUE=DATE:20071202.

##### Create DTEND

If set, returns [RFC5545] formatted string, otherwise FALSE.

Format

calendarComponent::createDtend()

Example

<?php .. . $str = $component->createDtend(); .. .

##### Delete DTEND

Remove DTEND from component.

Format

calendarComponent::deleteProperty( "DTEND" )

Example

<?php .. . $vevent->deleteProperty( "DTEND" ); .. .

##### Get DTEND

If set, returns property value, otherwise FALSE.

Format 1

calendarComponent::getProperty( "DTEND" )

output = dtendDate1

Format 2

calendarComponent::getProperty( "DTEND", FALSE , TRUE )

output = array( "value" => dtendDate1 , "params" => params2 )

Example

<?php .. . $dtend = $vevent->getProperty( "dtend" ); .. .

##### Set DTEND

Insert property value. If DATE value type is expected, "VALUE" = "DATE" must be set (in params2) otherwise DATE-TIME (default) value type is set.

If no timezone parameter (tz or tzidparam below) is set (i.e.local time) and config TZID is set, date-time values will be set WITH timezone from config. Notice, use function transformDateTime to change a datetime from one time zone to another.

Parameters will be ordered as prescribed in [RFC5545].

Format

calendarComponent::setProperty( "dtend", dtendDate [, params2 ] )

dtendDate1 = (array) ( "year" => (int) year , "month" => (int) month , "day" => (int) day [, "hour" => (int) hour , "min" => (int) min , "sec" => (int) sec [, "tz" => tz ]] ) dtendDate = (int) year , (int) month , (int) day [, (int) hour , (int) min , (int) sec [, tz ]] dtendDate = array( (int) year , (int) month , (int) day [, (int) hour , (int) min , (int) sec [, tz ]] ) dtendDate = (array) ( "timestamp" => (int) timestamp [,"tz" => tz]) // timestamp without tz will result in a UTC DATE-TIME // timestamp with tz=offset will result in a local DATE-TIME dtendDate = (string) date/datetime string* // Within the "VFREEBUSY" calendar component, // the time MUST be specified in the UTC DATE-TIME tz = (string) <timezone identifier> / offset // timezone will be used as tzidparam (below), if tzidparam not set offset = (int) (+/-)HHmm[ss] // (arr/str) local date + UTC offset // will result in a UTC DATE-TIME params2 = (array) ([ tzidparam/datetimeparam/dateparam ] *[,xparams]) tzidparam = "TZID" => (string) <timezone identifier> // output as local date-time with timezone identifier // if tzidparam="GMT"/"UTC" then // output date-time is suffixed by 'Z' datetimeparam = "VALUE" => "DATE-TIME" // default, output as date-time dateparam = "VALUE" => "DATE" // output as DATE, ex. all-day event xparams = (string) key => (string) value // key prefix "X-"
date/datetime string* recommended formats "20110625", "2011-06-25", "2011/06/26" "20110625051015", "20110625 051015" "20110625T051015", "20110625t051015" "2011-06-25 05:10:15", "2011-06-25T05:10:15", "2011-06-25t05:10:15" "2011/06/25 05:10:15", "2011/06/25T05:10:15", "2011/06/25t05:10:15" trailing characters (digits), if exists, will be interpreted as offset/timezone other string formats, acceptable by PHP strtotime function, may (would) work (notice date restriction)

Example 3

<?php .. . $vevent->setProperty( "dtend" , array( "year" =>, 2006, "month" => 8, "day"=> 11 ) , array( "VALUE" => "DATE" )); // end of an all-day event .. .

Example 4

<?php .. . $calendar->setConfig( 'TZID', 'Europe/Stockholm' ); .. . $vevent->setProperty( "dtend", 2006, 8, 11, 7, 30, 0 ); // output: DTEND;TZID=Europe/Stockholm:20060811T073000 .. .

### 3.2.16 DTSTAMP

The property indicates the date/time the instance of the iCalendar object was created and is OPTIONAL and MUST NOT occur more than once in VEVENT, VTODO, VJOURNAL and VFREEBUSY components. However, DTSTAMP is AUTOMATICALL§Y GENERATED in iCalcreator when creating a component.

DTSTAMP may be required when importing iCal files into some calendar software
(MS etc.), as well as (calendar) x-properties "X-WR-CALNAME", "X-WR-CALDESC" and
"X-WR-TIMEZONE", METHOD property (value PUBLISH etc.) and the (also auto created) UID property.

The value type for DTSTAMP is UTC DATE-TIME.

For methods and formatting, explore the CREATED property.

You can SORT calendar (components) on (asc) DTSTAMP values.

### 3.2.17 DTSTART

This property specifies when the calendar component begins. The property is OPTIONAL and MUST NOT occur more than once in VEVENT, VTODO, VJOURNAL and VFREEBUSY components. The property is REQUIRED, but MUST NOT occur more than once in STANDARD and DAYLIGHT components.

The default value type for DTSTART is DATE-TIME, can be set to a DATE value type.

For an "all-day event" and using timeless dates, example (2007-12-01)
DTSTART;VALUE=DATE:20071201
DTEND;VALUE=DATE:20071202. // opt., in effect midnight of the day before the date!!

For methods and formatting, explore the DTEND property.

### 3.2.20 EXDATE

This property defines the list of date/time exceptions for a recurring calendar component and is OPTIONAL and MAY occur more than once in VEVENT, VTODO, VJOURNAL components.

The default value type for EXDATE is DATE-TIME, can be set to a DATE value type.

##### Create EXDATE

If set, returns [RFC5545] formatted string, otherwise FALSE.

Format

calendarComponent::createExdate()

Example

<?php .. . $str = $component->createExdate(); .. .

##### Delete EXDATE

Remove EXDATE from component.

Format

calendarComponent::deleteProperty( "EXDATE" )

Example 1

<?php .. . $vtodo->deleteProperty( "EXDATE" ); .. .

Example 2

Delete EXDATE property no 2.

<?php .. . $vjournal->deleteProperty( "EXDATE", 2 ); .. .

Example 3

<?php .. . while( $vjournal->deleteProperty( "EXDATE" )) continue; .. .

##### Get EXDATE

If set, returns property value, otherwise FALSE.

Format 1

calendarComponent::getProperty( "EXDATE" )

output = exdates1

Format 2

calendarComponent::getProperty( "exdate", propOrderNo/FALSE, TRUE )

##### Set EXDATE

Insert property value.

The value type for EXDATE should match the DTSTART value type.

If DATE value type is set in params ("VALUE" = "DATE"), all timezone or offset in dates are ignored.
If no "VALUE" value type is set or if DATE-TIME value type or TZID value is set in params, DATE-TIME (default) value type is set.

If "TZID" is set in params, all timezone or offset in dates are ignored (note timestamp, below) and DATE-TIME value type is set.
If empty params and offset in 1st date, all remaining (non-timestamp) dates are set to UTC.
If no "TZID" is set in params and timezone in 1st date, all remaining dates are within this timezone and param "TZID" is set.
If none of the above rules are applicable, DATE-TIME and local date is set default.

Notice, use function transformDateTime to convert a datetime from one time zone to another.

EXDATEs are automatically sorted in ascending order (Y-m-d[-H-i-s]).

In spite of the fact that EXDATE may contain a (comma separated) list of values, a strong recommendation is to split a EXDATE "list" into multiple single EXDATE entries.

Parameters will be ordered as prescribed in [RFC5545].

Format

calendarComponent::setProperty( "exdate", exdates [, params [, propOrderNo ]] )

exdates1 = (array) ( date *[, date ] ) date = array( (int) year , (int) month , (int) day [, (int) hour , (int) min , (int) sec [, tz ]] ) date1 = (array) ( "year" => (int) year , "month" => (int) month , "day" => (int) day [, "hour" => (int) hour , "min" => (int) min , "sec" => (int) sec [, "tz" => tz ]] ) date = (array) ( "timestamp" => (int) timestamp [, "tz" => tz]) // timestamp without tz will result in a UTC DATE-TIME date = (string) date/datetime string* tz = (string) <timezone identifier> / offset // timezone will be used as tzidparam (below), if tzidparam not set offset = (int) (+/-)HHmm[ss] // (arr/str) local date + UTC offset will result in a UTC DATE-TIME params2 = (array) ([(datetimeparam/dateparam) / tzidparam] *[,xparams]) datetimeparam = "VALUE" => "DATE-TIME" // default, output as date-time dateparam = "VALUE" => "DATE" // output as DATE tzidparam = "TZID" => (string) <timezone identifier> xparams = (string) key => (string) value // key prefix "X-" propOrderNo = (int) order number // 1=1st, 2=2nd etc

##### Set RDATE

Insert property value.

The value type for RDATE should match the DTSTART value type.

If DATE value type is set in params ("VALUE" = "DATE"), all timezone or offset in dates are ignored.
If no "VALUE" value type is set or if DATE-TIME value type or TZID value is set in params, DATE-TIME (default) value type is set.

If "TZID" is set in params, all timezone or offset in dates are ignored (note timestamp, below) and DATE-TIME value type is set.
If empty params and offset in 1st date, all remaining (non-timestamp) dates are set to UTC.
If no "TZID" is set in params and timezone in 1st date, all remaining dates are within this timezone and param "TZID" is set.
If none of the above rules are applicable, DATE-TIME and local date is set default.

Notice, use function transformDateTime to convert a datetime from one time zone to another.

RDATEs are automatically sorted in ascending order (Y-m-d[-H-i-s]).

In spite of the fact that RDATE may contain a (comma separated) list of values, a strong recommendation is to split a RDATE "list" into multiple single RDATE entries.

Parameters will be ordered as prescribed in [RFC5545].

### 3.2.36 SEQUENCE

This property defines the revision sequence number of the calendar component within a sequence of revisions. The property is OPTIONAL and MUST NOT occur more than once in VEVENT, VTODO and VJOURNAL components.

It is monotonically incremented by the ORGANIZER's CUA (Calendar User Agent) each time the ORGANIZER makes a significant revision to the calendar component.
When the ORGANIZER makes changes to one of the following properties, the sequence number MUST be incremented: DTSTART, DTEND, DUE, RDATE, RRULE, EXDATE, EXRULE, STATUS. In addition, changes made by the ORGANIZER to other properties can also force the sequence number to be incremented. The ORGANIZER CUA MUST increment the sequence number when ever it makes changes to properties in the calendar component that the ORGANIZER deems will jeopardize the validity of the participation status of the Attendees. For example, changing the location of a meeting from one locale to another distant locale could effectively impact the participation status of the Attendees.

The value type of SEQUENCE is INTEGER.

<?php .. . $vevent->deleteProperty( "UID" ); .. .

##### Get UID

If set, returns property, otherwise FALSE.

Format 1

calendarComponent::getProperty( "UID" )

output = uid1

Format 2

calendarComponent::getProperty( "UID", FALSE , TRUE )

output = array( "value" => uid1 , "params" => xparams2 )

Example

<?php .. . $uid = $vevent->getProperty( "UID" ); .. .

##### Set UID

Insert property value, overrides any previously set or auto-created UID.

Do NOT use an integer UID or only a component name in UID (ex. "vevent"), this may cause malfunction in iCalcreator object method setComponent with index or UID argument.

Format

calendarComponent::setProperty( "uid", uid [, xparams ] )

uid1 = (string) Value type TEXT xparams2 = array( *[ (string) key => (string) value ] ) // key prefix "X-"

Example

<?php .. . $vevent->setProperty("uid","20070803T194810CEST-0123U3PXiX@kigkonsult.se"); .. .

BUT, due to poorly created iCal media files, a digit UID is accepted in the setProperty( UID ) and parse() methods. Do check for component digit UIDs and remove it (will force a (auto) UID recreation) or (re-)set it manually.

<?php .. . if( ctype_digit( $vevent->getProperty( "UID" ))) $vevent->deleteProperty( "UID" ); .. .

# 4 iCalUtilityFunctions

iCalUtilityFunctions class contains static functions used by iCalcreator, also usable outside the iCalcreator class.

"External" functions
  4.1 convEolChar
  4.2 createTimezone
  4.3 ms2phpTZ
  4.4 transformDateTime
"Internal" functions
  4.5 Misc. date/duration/timestamp util. functions

#### 4.1 convEolChar

Removes any line-endings that may include spaces or tabs (\t) and convert all line endings (iCal default "\r\n"), takes care of "\r\n", "\r" and "\n" and mixed "\r\n"+"\r", "\r\n"+"\n".

Returns string with controlled and corrected line endings.

Format

iCalUtilityFunctions::convEolChar( str, nl )

str = (string) string to adjust nl = line ending to convert to

[index] [top] [up]

#### 4.2 createTimezone

The function, applied on a iCalcrator object instance and using a PHP valid timezone (as argument) creates vtimezone, standard and daylight components, based on PHP DateTimeZone class and the time zone transition dates. (PHP 5 >= 5.2.0)

Recommendation is to call the function after editing components (and without (period) from/to arguments, below), it will automatically create timezone components, starting seven month before lowest DTSTART value and end 18 month after the higest.

If no time zone transition exists within date arguments or within the "DTSTART"s span, then the time zone transition with the highest transistion date before "from" date is used as base. If still missing, timezone components are created, using current date.

Note, only when timezone NOT is UTC. For dates with UTC DATE-TIME, read this!

FALSE is returned if not using a PHP valid timezone.

Format

iCalUtilityFunctions::createTimezone( calendar, timezone [, xprops, [, from [, to ]]] )

calendar = (object) iCalcreator instance timezone = (string) an PHP (DateTimeZone) valid timezone xprops = (array) ( *[ x-propName => value ] ), timezone non-standard properties from = (int) timestamp, period start date* to = (int) timestamp, period end date* * if empty "from" and "to" arguments, the calendar getProperty method (with "DTSTART" as argument) is used to get the lowest (modified, minus 7 month) and highest (modified, plus 15 month) dates.

Example

<?php .. . $tz = "Europe/Stockholm"; $config = array( "unique_id" => "kigkonsult.se", "TZID" => $tz ); $c = new vcalendar( $config ); $c->setProperty( "X-WR-TIMEZONE", $tz ); .. . .. . // insert components or parse an iCal file .. . $xprops = array( "X-LIC-LOCATION" => $tz ); iCalUtilityFunctions::createTimezone( $c, $tz, $xprops ); .. .

Output example (when using iCalcreator object createCalendar or returnCalendar methods):

BEGIN:VTIMEZONE TZID:Europe/Stockholm X-LIC-LOCATION:Europe/Stockholm BEGIN:STANDARD DTSTART:20111030T003000 TZOFFSETFROM:+0200 TZOFFSETTO:+0100 TZNAME:CET END:STANDARD BEGIN:DAYLIGHT DTSTART:20110327T002000 TZOFFSETFROM:+0100 TZOFFSETTO:+0200 TZNAME:CEST END:DAYLIGHT END:VTIMEZONE

[index] [top] [up]

#### 4.3 ms2phpTZ

Conversion (very simple) of a MS timezone to a PHP5 valid (Date-)timezone,
matching (MS) UTC offset and time zone descriptors, based on PHP DateTimeZone class. (PHP 5 >= 5.2.0)

If TRUE is returned, the MS timezone argument (below) is converted to a PHP5 time zone, otherwise unaltered.

Format

iCalUtilityFunctions::ms2phpTZ( timezone )

timezone = (string) MS timezone (input), PHP5 timezone (output)

Example

<?php .. . $search = '"(UTC-06:00) Central Time (US & Canada)"'; echo "MS tz:'$search'<br>\n"; if( FALSE !== iCalUtilityFunctions::ms2phpTZ( $search )) echo "PHP tz:'$search'<br>\n"; .. .

[index] [top] [up]

#### 4.4 transformDateTime

Transforms a datetime from a time zone to another. (Requires PHP >= 5.2.0 and PHP DateTimeZone acceptable time zones).

FALSE is returned if not using a "strtotime" acceptable datetime string or unacceptable PHP time zones. If TRUE, the dateTime argument (below) is converted to the new time zone, otherwise unaltered.

A DATE input (<year><month><day>) will be expanded to a DATETIME (<year><month><day>000000) before transform.

Format

iCalUtilityFunctions::transformDateTime( dateTime, timezoneFrom [, timezoneTo [, format ]] )

dateTime = (array) ( "year" => (int) year // input , "month" => (int) month , "day" => (int) day [, "hour" => (int) hour , "min" => (int) min , "sec" => (int) sec ] ) dateTime = (array) ( (int) year // input , (int) month , (int) day [, (int) hour , (int) min , (int) sec ] ) dateTime = (array) ( "timestamp" => (int) timestamp ) // input dateTime = (string) datetime string* // input dateTime = (string) datetime string // on successful output timezoneFrom = (string) a PHP (DateTimeZone) valid time zone timezoneTo = (string) a PHP (DateTimeZone) valid time zone, default "UTC" format = (string) output format (any date formatting, default "Ymd\THis")
datetime string* recommended formats "20110625", "2011-06-25", "2011/06/26" "20110625051015", "20110625 051015" "20110625T051015", "20110625t051015" "2011-06-25 05:10:15", "2011-06-25T05:10:15", "2011-06-25t05:10:15" "2011/06/25 05:10:15", "2011/06/25T05:10:15", "2011/06/25t05:10:15" other string formats, acceptable by PHP strtotime function, may (would) work (notice date restriction)

Example

Convert from time zone "Europe/Stockholm" to "UTC"

<?php .. . $d = date( "Y-m-d H:i:s" ); $tzFr = "Europe/Stockholm"; if( FALSE !== iCalUtilityFunctions::transformDateTime( $d, $tzFr )) $event->setProperty( "dtstart", $d."Z" ); else $event->setProperty( "dtstart", $d, array( "TZID" => $tzFr )); .. .
