<?php
$cookie_jar = tempnam('./tmp','cookie');
$ch = curl_init();
curl_setopt($ch, curlopt_url,'登陆地址');
curl_setopt($ch, curlopt_post, 1);
$request = 'username=xxx&pwd=xxx';
curl_setopt($ch, curlopt_postfields, $request);//传递数据
curl_setopt($ch, curlopt_cookiejar, $cookie_jar);//把返回来的cookie信息保存在$cookie_jar文件中
curl_setopt($ch, curlopt_returntransfer, 1);//设定返回的数据是否自动显示
curl_setopt($ch, curlopt_header, false);//设定是否显示头信息
curl_setopt($ch, curlopt_nobody, false);//设定是否输出页面内容
curl_exec($ch);
curl_close($ch); //get data after login

$ch2 = curl_init();
curl_setopt($ch2, curlopt_url, '查看地址');
curl_setopt($ch2, curlopt_header, false);
curl_setopt($ch2, curlopt_returntransfer, 1);
curl_setopt($ch2, curlopt_cookiefile, $cookie_jar);
$orders = curl_exec($ch2);

echo $orders;
curl_close($ch2);// 实践证明很稳定:)
