curl_errno
While working with curl i got the following error: "empty reply from server".
Searching Google gave no solutions. So i just tried to replace the spaces from the url to %20 and it worked!
Hope this helps someone.

For a 404 response to actually trigger an error as the example seems to be trying to demonstrate the following option should be set:
curl_setopt($ch,CURLOPT_FAILONERROR,true);
As per http://curl.haxx.se/libcurl/c/libcurl-errors.html
CURLE_HTTP_RETURNED_ERROR (22)
This is returned if CURLOPT_FAILONERROR is set TRUE and the HTTP server returns an error code that is >= 400. (This error code was formerly known as CURLE_HTTP_NOT_FOUND.)

If you want to fetch the error message, make sure you fetch it before you close the current cURL session or the error message will be reset to an empty string.

The return value for this function is actually an english description of the error, rather than an error number, FYI.
