function getURL($url){ 
     $ch = curl_init(); 
     curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE); 
     curl_setopt($ch, CURLOPT_HEADER, 0); 
     curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1); 
     curl_setopt($ch, CURLOPT_URL, $url); 
     $tmp = curl_exec($ch); 
     curl_close($ch); 
     if ($tmp != false){ 
      return $tmp; 
     } 
    }
