watch your case when using methods (POST and GET)...it must be always uppercase. in case of you write it in lower case it wont work.

Examples
Example #1 Fetch a page and send POST data
<?php
$postdata = http_build_query(
array(
'var1' => 'some content',
'var2' => 'doh'
)
);
$opts = array('http' =>
array(
'method' => 'POST',
'header' => 'Content-type: application/x-www-form-urlencoded',
'content' => $postdata
)
);
$context = stream_context_create($opts);
$result = file_get_contents('http://example.com/submit.php', false, $context);
?>
Example #2 Ignore redirects but fetch headers and content
<?php
$url = "http://www.example.org/header.php";
$opts = array('http' =>
array(
'method' => 'GET',
'max_redirects' => '0',
'ignore_errors' => '1'
)
);
$context = stream_context_create($opts);
$stream = fopen($url, 'r', false, $context);
// header information as well as meta data
// about the stream
var_dump(stream_get_meta_data($stream));
// actual data at $url
var_dump(stream_get_contents($stream));
fclose($stream);
?>
Notes
Note: Underlying socket stream context options
Additional context options may be supported by the underlying transport For http:// streams, refer to context options for the tcp:// transport. For https:// streams, refer to context options for the ssl:// transport.
Note: HTTP status line
When this stream wrapper follows a redirect, the wrapper_data returned by stream_get_meta_data() might not necessarily contain the HTTP status line that actually applies to the content data at index 0.The first request returned a 301 (permanent redirect), so the stream wrapper automatically followed the redirect to get a 200 response (index = 4).array ( 'wrapper_data' => array ( 0 => 'HTTP/1.0 301 Moved Permantenly', 1 => 'Cache-Control: no-cache', 2 => 'Connection: close', 3 => 'Location: http://example.com/foo.jpg', 4 => 'HTTP/1.1 200 OK', ...

Note that if you set the protocol_version option to 1.1 and the server you are requesting from is configured to use keep-alive connections, the function (fopen, file_get_contents, etc.) will "be slow" and take a long time to complete. This is a feature of the HTTP 1.1 protocol you are unlikely to use with stream contexts in PHP.
Simply add a "Connection: close" header to the request to eliminate the keep-alive timeout:
<?php
// php 5.4 : array syntax and header option with array value
$data = file_get_contents('http://www.example.com/', null, stream_context_create([
'http' => [
'protocol_version' => 1.1,
'header' => [
'Connection: close',
],
],
]));
?>

If you use the proxy server and encounter an error "fopen(http://example.com): failed to open stream: HTTP request failed! HTTP/1.0 400 Bad Request" note that in many situations you need also set the parameter "request_fulluri" to "true" in your stream options. Without this option the php script sends the empty request to the server as "GET / HTTP/0.0" and the proxy server replies to it with the "HTTP 400" error.
For example (working sample):
<?php
$stream = stream_context_create(Array("http" => Array("method" => "GET",
"timeout" => 20,
"header" => "User-agent: Myagent",
"proxy" => "tcp://my-proxy.localnet:3128",
'request_fulluri' => True /* without this option we get an HTTP error! */
)));
if ( $fp = fopen("http://example.com", 'r', false, $stream) ) {
print "well done";
}
?>
P>S> PHP 5.3.17

Remember to match content with Content-type:
<?php
$data = array(
'var1' => 'some content',
'var2' => 'doh'
);
$opts = array('http' =>
array(
'method' => 'POST',
'header' => 'Content-type: application/json', // here...
'content' => json_encode($data) // and here.
)
);
. . .

I had quite a bit of trouble trying to make a request with fopen through a proxy to a secure url. I kept getting a 400 Bad Request back from the remote host. It was receiving the proxy url as the SNI host. In order to get around this I had to explicity set the SNI host to the domain I was trying to reach. It's apparently the issue outlined in this bug:
https://bugs.php.net/bug.php?id=63519
<?php
$domain = parse_url($file, PHP_URL_HOST);
$proxy_string = "tcp://" . WP_PROXY_HOST . ":" . WP_PROXY_PORT;
$opts = array(
'http' => array( 'proxy' => $proxy_string ),
'ssl' => array( 'SNI_enabled' => true, 'SNI_server_name' => $domain));
$context = stream_context_create($opts);
$handle = fopen( $file, 'r', false, $context );
?>
