详解php中curl返回false的解决办法

首先来看一个封装的curl函数

function request_post($url = '', $param = '') {
 if (empty($url) || empty($param)) {
 return false;
 $postUrl = $url;
 $curlPost = $param;
 $curl = curl_init();//初始化curl
 curl_setopt($curl, CURLOPT_URL,$postUrl);//抓取指定网页
 curl_setopt($curl, CURLOPT_HEADER, 0);//设置header
 curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);//要求结果为字符串且输出到屏幕上
 curl_setopt($curl, CURLOPT_POST, 1);//post提交方式
 curl_setopt($curl, CURLOPT_POSTFIELDS, $curlPost);//提交的参数
 $data = curl_exec($curl);//运行curl
 curl_close($curl);
