get_headers — Fetches all the headers sent by the server in response to a HTTP request
get_headers() returns an array with the headers sent by the server in response to a HTTP request.
The target URL.
If the optional format parameter is set to 1, get_headers() parses the response and sets the array's keys.
Returns an indexed or associative array with the headers, or FALSE on failure.
Example #1 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 )
