[ACCEPTED]-What is the easiest way to use the HEAD command of HTTP in PHP?-head
You can do this neatly with cURL:
<?php
// create a new cURL resource
$ch = curl_init();
// set URL and other appropriate options
curl_setopt($ch, CURLOPT_URL, "http://www.example.com/");
// This changes the request method to HEAD
curl_setopt($ch, CURLOPT_NOBODY, true);
// grab URL and pass it to the browser
curl_exec($ch);
// Edit: Fetch the HTTP-code (cred: @GZipp)
$code = curl_getinfo($ch, CURLINFO_HTTP_CODE);
// close cURL resource, and free up system resources
curl_close($ch);

As an alternative to curl you can use the 4 http context options to set the request 3 method to HEAD. Then open a (http wrapper) stream 2 with these options and fetch the meta data.
$context = stream_context_create(array('http' =>array('method'=>'HEAD')));
$fd = fopen('http://php.net', 'rb', false, $context);
var_dump(stream_get_meta_data($fd));
fclose($fd);

Even easier than curl - just use the PHPget_headers()function 7 which returns an array of all header info 6 for any URL you specify. And another real 5 easy way to check for remote file existence 4 is to usefopen()and try to open the URL in read 3 mode (you'll need to enable allow_url_fopen 2 for this).
Just check out the PHP manual 1 for these functions, it's all in there.
Use can use Guzzle Client, it use CURL library but more 2 simple and optimized.
installation:
composer require guzzlehttp/guzzle
example in your case:
// create guzzle object
$client = new \GuzzleHttp\Client();
// send request
$response = $client->head("https://example.com");
// extract headers from response
$headers = $response->getHeaders();
Fast 1 and easy.
