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');
?>
