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.
(PHP 4 >= 4.0.3, PHP 5)
curl_error — Return a string containing the last error for the current session
Returns a clear text error message for the last cURL operation.
A cURL handle returned by curl_init().
Returns the error message or '' (the empty string) if no error occurred.
Example #1 curl_error() example
// Create a curl handle to a non-existing location
$ch = curl_init('http://404.php.net/');
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
if(curl_exec($ch) === false)
echo 'Curl error: ' . curl_error($ch);
echo 'Operation completed without any errors';
// Close handle
For a 404 response to actually trigger an error as the example seems to be trying to demonstrate the following option should be set:
As per http://curl.haxx.se/libcurl/c/libcurl-errors.html
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.
