help with curl

[osusano]

$_url = "http://xxx.xxx.xxx.xxx:xxx/cgi-bin/sendsms";
$params = "username=$user&password=$password&to=$mobile&from=$access&text=$msg";

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL,$_url);
curl_setopt($ch, CURLOPT_POST,1);
curl_setopt($ch, CURLOPT_POSTFIELDS,$params);
curl_exec ($ch);
curl_close ($ch);

just wondering maybe people can help me with my curl scripting..

basically this will just pass th value of the parameters to another url.

thank you in advance.
