This function now uses the default stream context, which can be set/changed with the stream_context_set_default() function.
Examples:
get_headers() example
<?php $url = 'http://www.example.com'; print_r(get_headers($url)); print_r(get_headers($url, 1)); ?>
The above example will output something similar to:
Array ( [0] => HTTP/1.1 200 OK [1] => Date: Sat, 29 May 2004 12:28:13 GMT [2] => Server: Apache/1.3.27 (Unix) (Red-Hat/Linux) [3] => Last-Modified: Wed, 08 Jan 2003 23:11:55 GMT [4] => ETag: "3f80f-1b6-3e1cb03b" [5] => Accept-Ranges: bytes [6] => Content-Length: 438 [7] => Connection: close [8] => Content-Type: text/html ) Array ( [0] => HTTP/1.1 200 OK [Date] => Sat, 29 May 2004 12:28:14 GMT [Server] => Apache/1.3.27 (Unix) (Red-Hat/Linux) [Last-Modified] => Wed, 08 Jan 2003 23:11:55 GMT [ETag] => "3f80f-1b6-3e1cb03b" [Accept-Ranges] => bytes [Content-Length] => 438 [Connection] => close [Content-Type] => text/html )
get_headers() using HEAD example
<?php // By default get_headers uses a GET request to fetch the headers. If you // want to send a HEAD request instead, you can do so using a stream context: stream_context_set_default( array( 'http' => array( 'method' => 'HEAD' ) ) ); $headers = get_headers('http://example.com'); ?>
