PHP 利用curl发送指定远程IP请求

比如我要将baidu.com 解析到IP121.12.XX.XX下，那么可以这样

           $url = 'www.baidu.com'; 

<span style="white-space:pre"></span>    $proxy = '121.14.XX.XX:80';            $ch = curl_init();            curl_setopt($ch, CURLOPT_URL,$url);            curl_setopt($ch, CURLOPT_PROXY, $proxy);            curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);            curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);//             curl_setopt($ch, CURLOPT_HEADER, 1); 如果不注释这行会打印出header信息            $result = curl_exec($ch);            curl_close($ch);
