[ILUG-Webdev] PHP Libcurl detecting a timeout

Hi All, 

I've being doing some google work here with this problem, and don't
seem to be able to come up with a good enough answer.

My problem is with Libcurl compiled into PHP. I am using it to post some
XML to a server (See method below.), however I don't seem to be able to
detect correctly if there was a timeout in connecting to the server, or
curl otherwise fails.

This has the effect of passing what should be an invalid trasaction
along. Anyone got a pointer or 77 for me. 

Thanks in advance 
AJ

private function PostTransaction ($xml,$server) {

                settype($xml, "string");
                settype($server, "string");
                // Begin CURL.
                $curl = curl_init();     

                // CURL Options.
                curl_setopt($curl, CURLOPT_URL, $server);
                curl_setopt($curl, CURLOPT_POST, 1); 
                curl_setopt($curl, CURLOPT_USERAGENT, "Geeky Option"); 
                curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1); 
                curl_setopt($curl, CURLOPT_POSTFIELDS, $xml);
                curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, FALSE);
                curl_setopt($curl, CURLOPT_CONNECTTIMEOUT, 30);
                curl_setopt($curl, CURLOPT_DNS_CACHE_TIMEOUT, 600);
                // Execute the CURL command and get the result.
                $response = curl_exec ($curl);    
                curl_close ($curl); 
                if(!$response) {
                                return false;
                        }
                return $response;
                }
