<form method="post" action="2.php"> 用户名： <input type='text' name="loginname"><br> 密码：<input type="password" name='loginpass'><br> <input type='submit' value="submit"></form>
header('Content-Type:text/html;Charset=utf-8');if ($_POST['loginname'] == 'lee' && $_POST['loginpass'] == '123456') { header('location:http://bbs.csdn.net');} else { } header('Content-type:text/html;Charset=utf-8'); $user = 'lee'; //登陆用户名 $pass = '123456'; //登陆密码 $post_fields = "loginname={$user}&loginpass={$pass}";$ch = curl_init(); curl_setopt($ch,CURLOPT_URL,'http://localhost/2.php');curl_setopt($ch,CURLOPT_POST,1);curl_setopt($ch,CURLOPT_POSTFIELDS,$post_fields);curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); curl_exec($ch);curl_close($ch); echo curl_exec($ch);
另外你的2.php是跳转了，并没有返回内容。
改成echo file_get_contnets('location:http://bbs.csdn.net'); 试试
header('location:http://bbs.csdn.net');
形成的 http 头
HTTP/1.1 302 Found
Date: Wed, 26 Feb 2014 09:16:38 GMT
location: http://bbs.csdn.net
Content-Length: 0
Content-Type: text/html;Charset=utf-8
你不跟着跳转吗？
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);
header('location:http://bbs.csdn.net');

谢谢斑竹的帮忙 我改成了这样
1.php
header('Content-type:text/html;Charset=utf-8'); $user = 'lee'; //登陆用户名 $pass = '123456'; //登陆密码 $post_fields = "loginname={$user}&loginpass={$pass}";$ch = curl_init(); curl_setopt($ch,CURLOPT_URL,'http://localhost/2.php');curl_setopt($ch,CURLOPT_POST,1);curl_setopt($ch,CURLOPT_POSTFIELDS,$post_fields);curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); curl_setopt($ch, CURLOPT_FOLLOWLOCATION,true);curl_exec($ch);curl_close($ch); header('Content-Type:text/html;Charset=utf-8');if ($_POST['loginname'] == 'lee' && $_POST['loginpass'] == '123456') { header('location:http://bbs.csdn.net');} else { } #1 不是说了吗？
echo curl_exec($ch);
你不输出结果怎么能行？
