Приклад #2 get_headers() 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:
$context = stream_context_create(
[
'http' => array(
'method' => 'HEAD'
)
]
);
$headers = get_headers('http://example.com', false, $context);
?>
