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)

Example #2
get_headers(3) 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');
?>
