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));
?>
