get_headers

get_headers

(PHP 5)

get_headers -- Fetches all the headers sent by the server in response to a HTTP request

Description

array get_headers ( string url [, int format] )

get_headers() returns an array with the headers sent by the server in response to a HTTP request. Returns FALSE on failure and an error of level E_WARNING will be issued.

If the optional format parameter is set to 1, get_headers() parses the response and sets the array's keys.

Note: Since PHP 5.1.3 this function uses the default stream context, which can be set/changed with the stream_context_get_default() function.

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
