XML : Create job in jenkins via PHP (POST with XML)

I'm kinda beginning with Jenkins and now i'm facing a problem i need create a job in jenkins sending a request to create a new job i tried to do with CURL but i had no luck and no abilities to make it happen. I still need pass the user and the token once that the server has to log in to do the stuff.

What i have now:

  $xml = '<project>              ...          </project>';        $url = 'http://user:token@localhost:8080/createItem?name=newjobname';        $ch = curl_init();        curl_setopt($ch,CURLOPT_URL, $url);      curl_setopt($ch, CURLOPT_POSTFIELDS, "xmlRequest=" . $xml);      curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);      curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 300);      $result = curl_exec($ch);        curl_close($ch);    

Any ideas ?
