PHP Curl get HTTP code, not whole document

问题:

I'm using curl in PHP to check the HTTP code when requesting some files, I'm trying to make my speed run faster so I'm wondering is there a way to make it get the HTTP code without actually getting the web page from the remote host

回答1:

Set CURLOPT_NOBODY to true. This means that rather than preforming a GET or POST request, a HEAD request will be preformed so the remote server will only return the HTTP header.

curl_setopt($ch, CURLOPT_NOBODY, true);

There is also some example code in this answer
