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.
(PHP 4 >= 4.0.3, PHP 5, PHP 7)
curl_error — Return a string containing the last error for the current session
$ch
)Returns a clear text error message for the last cURL operation.
Returns the error message or '' (the empty string) if no error occurred.
Example #1 curl_error() example
<?php
// 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);
}
else
{
echo 'Operation completed without any errors';
}
// Close handle
curl_close($ch);
?>
If you want to fetch the error message, make sure you fetch it before you close the current cURL session or the error message will be reset to an empty string.
For a 404 response to actually trigger an error as the example seems to be trying to demonstrate the following option should be set:
curl_setopt($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.)

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.
