// 设置cURL 参数，要求结果保存到字符串中还是输出到屏幕上。
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
//是否获得跳转后的页面

$data = curl_exec($ch);
curl_close($ch);
echo $data;
?>

<?php
function curl_post($url, $arr_data){
   $post_data = http_build_query($url_data);

    curl_setopt($ch, CURLOPT_POST, 1);
    curl_setopt($ch,  CURLOPT_POSTFLELDS, $post_data);
