//http request interface
function curl_http_request($param,$url)
{
 $ch = curl_init();
 $curl_url = $url."?".$param;
 curl_setopt($ch, CURLOPT_URL , $curl_url);
 curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, FALSE); //Disable certificate
 curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE);
 curl_setopt ($ch, CURLOPT_HEADER, 0); //Header file information for data flow Output
 curl_setopt($ch, CURLOPT_POST, 1);
 curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);//Do not output directly, return to variable
 $curl_result = curl_exec($ch);
 curl_close($ch);

 return $curl_result;
