一般json编码格式是{key:value},而表单编码方式则是 key=value&key2=value2。

直接上代码：

代码中这样传传过去 就是FormData方式

$data ="id=230&rid=3533&name=王炎&id_number=35018119800&mobile=1139460";

echo posturl('https://xb.xbUrl',$data);
function posturl($url,$data){

        $headerArray =array("Content-type:application/x-www-form-urlencoded;charset='utf-8'","Accept:application/x-www-form-urlencoded");                           
        $curl = curl_init();
        curl_setopt($curl, CURLOPT_URL, $url);
        curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, FALSE);
        curl_setopt($curl, CURLOPT_SSL_VERIFYHOST,FALSE);
        curl_setopt($curl, CURLOPT_POST, 1);
        curl_setopt($curl, CURLOPT_POSTFIELDS, $data);
        curl_setopt($curl,CURLOPT_HTTPHEADER,$headerArray);
        curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);
        $output = curl_exec($curl);
        echo $output;
        curl_close($curl);
}
