Find file size of a remote file without downloading it

Question

This solution works for image or pdfs, however, when I try it with text or javascript files curl_exec return false. Why?

It works for me and I'm getting `21705` as the output. Is this different for you? — Amal Murali, Nov 06 '13 at 18:23
Yes `curl_exec` returns `false`. You tried with url https://raw.github.com/jquery/jquery/master/src/ajax.js? — dev.e.loper, Nov 06 '13 at 18:23

This probably has to do with GitHub URL being https. You can tell cURL go ignore the certificate check, by doing:

curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, 0);

If this doesn't solve the issue, you can add a echo curl_error($curl) before curl_close( $curl ); -- it might help you with debugging.

`curl_error($curl)` after the `curl_exec()` yields "SSL certificate problem: unable to get local issuer certificate" here, confirming https being the root of the problem. – ax. Nov 06 '13 at 18:37
