help with curl

Dear All, I have a script that uses curl to execute an http request now I use the same code for two different servers. And it works on the first server but not the second. I have stored the URL that it generates on the server that doesnt work and if I paste it into the address bar of the browser it works but somehow the script doesnt execute it.

       $ch = curl_init();    // initialize curl handle
       curl_setopt($ch, CURLOPT_URL,$url); // set url to post to
       curl_setopt($ch, CURLOPT_FAILONERROR, 1);
       curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);// allow redirects
       curl_setopt($ch, CURLOPT_RETURNTRANSFER,1); // return into a variable
       curl_setopt($ch, CURLOPT_TIMEOUT, 8); // times out after 4s
       curl_setopt($ch, CURLOPT_GET, 1); // set POST method
       curl_setopt($ch, CURLOPT_POSTFIELDS, $dat); // add POST
       curl_setopt($ch, CURLOPT_PORT, $port); // set POST method
       $result = curl_exec($ch); // run the whole process

now is there anything that can be causing this not to execute? I have increasd the timeout to 8 seconds (is this enough). COuld there be a problem with the server not being able to execute a URL in that way? Is there anything else I can do to trouble shoot this? IF the URL is as follows: http://www.sdfsfjs.com?username=hello&password=goodbye do I need to set the GET variable string seperately in the CURLOPT_POSTFIELDS or can I just send it as one string?
