PHP (PHP: Hypertext Preprocessor) is a scripting language that helps people make web pages more interactive, by allowing them to do more things.
A website programmed with PHP can have pages that are password protected. A website with no programming cannot do this without other complex things. Standard PHP file extensions are: .php .php3 or .phtml, although a web server can be set up to use any extension.[5][6]
Its structure was influenced by many languages like C, Perl, Java, C++, and even Python. It is considered to be free software by the Free Software Foundation.[7]
Wikipedia, which runs on MediaWiki, uses the PHP scripting language.
History[change | change source]
PHP was first created by a man called Rasmus Lerdorf in 1995.[8] It is now developed and improved by a large team of people.
Example[change | change source]
An example Hello World program:
<?php
echo "Hello, World!";
?>
It is common to put PHP code inside a HTML document, for example:
<!DOCTYPE html>
<html>
<head>
<title>Hello World</title>
</head>
<body>
<?= '<p>Hello World</p>'; ?>
</body>
</html>
