php用账号密码模拟登陆解决办法

php用账号密码模拟登陆

http://112.78.104.13

账号：zm1000，密码a123456，我想用php模拟登陆，但是总是不行，是不是提交方式不对？求大神解答！

或者提取出cookie来也行，但是好像又不支持cookie
------解决思路----------------------
1、http://112.78.104.13 是框架页。含有公共变量和函数
2、含登录框的框架是 http://112.78.104.13/app/member
3、表单目标页是 http://112.78.104.13/app/member/login.php
4、登录后返回

<script><br />top.uid = '360eae3m12904263l134939190';<br />top.langx = 'zh-tw';<br />top.liveid = 'cbcfc6cdcec29bcdccc9cd'<br />top.casino = 'SI2';<br />top.hot_game = '';<br />top.hasLogin = 'login';<br /></script><br /><script>window.location.href = 'http://112.78.104.13/app/member/FT_index.php?mtype=3&uid=360eae3m12904263l134939190&langx=zh-tw';</script><br />

仅 php 只能做到这里，虽然可析出跳转的目标页，但数据是由 js 产生的。只能得到页面框架

参考代码

$url = 'http://112.78.104.13/app/member';<br />$url1 = 'http://112.78.104.13/app/member/login.php';<br />$d = array('username' => 'zm1000', 'passwd' => 'a123456');<br /><br />//echo file_get_contents($url);<br />//print_r(get_headers($url));<br /><br />echo postdata($url1, $d);<br /><br />function postdata($url, $data){<br />    $opts = array(<br />        'http' => array(<br />            'method' => 'POST',<br />            'header' => 'content-type:application/x-www-form-urlencoded',<br />            'user_agent' => $_SERVER['HTTP_USER_AGENT'],<br />            'content' => http_build_query($data)<br />        )    <br />    );<br />    $context = stream_context_create($opts);<br />    $result = file_get_contents($url, false, $context);<br />    return $result;<br />}

只为展示使用 file_get _contents 模拟提交
