How to send an incomplete HTTP request from PHP?

I need to check if remote file are online and they didn't change. The problem is that those files are big, so I want to read the http header only and then abort the request. The result would be based on response status code and content length field.

How can I do it in PHP?

You can use the get_headers() function.

If you prefer cURL, you can use CURLOPT_NOBODY:

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_HEADER, TRUE);
curl_setopt($ch, CURLOPT_NOBODY, TRUE); 
curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE);

$headers = curl_exec($ch);
