THINKPHP网站登录页在本地测试可以正常登录，在服务器却无法正常跳转

为什么我的网站登录页在本地测试可以正常登录，在服务器却无法正常跳转呢？

                        
                            
                                                            
                            
                                                            
                            <?php if($_SESSION['login_time']>=3):?>                            
                            <?php endif;?>

LoginAction.class.php的代码：

url 重写没有生效

url 重写没有生效

RewriteEngine onRewriteCond %{REQUEST_FILENAME} !-dRewriteCond %{REQUEST_FILENAME} !-fRewriteRule ^(.*)$ index.php?/$1 [QSA,PT,L]

本地是windows7 32位+php now环境
服务器是LINUX+wdcp服务器/虚拟主机管理系统

还可能是 session 无效

问题查出来了，是控制器的最后一句语句不起作用：
header("Location:" . $back);
而$back = ‘/usercontent-index.html’
这个语句不知怎的在本地可以跳转，在网站上却不行

改成这样也不行啊：

$strs = explode('.',$back);   $this->redirect($strs[0]);  

 if (!$back) {                $back =  U('Usercontent/index');            }            if (strpos(strtolower($back), 'eintro') !== false) {                $back = U('Fund/asset');            }            if (!$back || strpos(strtolower($back), 'login') !== false || strpos(strtolower($back), 'register') !== false) {                $back = U('Usercontent/index');            }

不对！
http://www.onloan.com.cn/usercontent-index.html
会转到
http://www.onloan.com.cn/login-index.html

所以要么是登录程序有问题（无法确认是用户），要么是 session 失效

session保存目录可写？

fwrite($fp,'username: ',$_SESSION['username']); 这句无法输出

大麦加油！关注、学习！

\ThinkPHP\Common\functions.php

$name['path'] = "/Runtime";  //thinkphp目录下if(isset($name['path'])) session_save_path($name['path']);

楼上这样设本地都无法登录了，

晕死，是PHP版本的问题，以下同样的代码，本地返回true,服务器返回false,
跟踪结果，同样是SESSION为空

protected function isLogin() {if (!empty($_SESSION['username']) && !empty($_SESSION['uid'])) {            $this->updateOnlineTime()；             return true;        } else {            return false;        }}

 $fp = fopen('./qerr26.txt','w+'); fwrite($fp,'ok'); session_start();   $_SESSION['XXX'] ='123'; fwrite($fp,'SESSIONXXX: ',$_SESSION['XXX']); fwrite($fp,'username: ',$_SESSION['username']); fwrite($fp,'uid: ',$_SESSION['uid']); fclose($fp); 

也可能是你的服务器 php 版本低了

$url = 'http://www.onloan.com.cn/usercontent-index.html';print_r(get_headers($url));echo file_get_contents($url);

Array(    [0] => HTTP/1.1 200 OK    [1] => Date: Sun, 05 Oct 2014 05:57:52 GMT    [2] => Content-Type: text/html    [3] => Content-Length: 265    [4] => Connection: close    [5] => Server: nginx/1.0.15    [6] => X-Powered-By: PHP/5.2.17p1)

再有，你的服务器用的是 nginx
能支持 .htaccess 吗？

你在登录页打印一下传入的参数看看
这样无目标的瞎猜是没有用的

        $map["u_username|u_email|u_phone"] = $username;        $map["u_password"] = $password;		        $user = M("user")->where($map)->find();		 $fp = fopen('./qerr28.txt','w+'); fwrite($fp,'username: ',$user["u_username"]); fwrite($fp,'uid: ',$user["id"]); fclose($fp); 

我不知道到哪里看TRACE的跟踪信息，在哪个目录的哪个日志文件里？

20楼的代码有错，更正为：

 $map["u_username|u_email|u_phone"] = $username; $map["u_password"] = $password;          $user = M("user")->where($map)->find();          $fp = fopen('./qerr28.txt','w+'); fwrite($fp,' username: ' . $user["u_username"]); fwrite($fp,' uid: ' . $user["id"]); fclose($fp); 

    protected function isLogin() {		 //cjq add $fp = fopen('./qerr26.txt','w+'); fwrite($fp,'ok'); $_SESSION['XXX'] ='123'; fwrite($fp,' SESSIONXXX:  ' . $_SESSION['XXX']); fwrite($fp,' username: ' . $_SESSION['username']); fwrite($fp,' uid: ' . $_SESSION['uid']); fclose($fp); 

php.ini 中 session.auto_start 的值是什么？

保存session的变量没有成功，有可能是php版本问题，对于session 环境参数设置可能不一样，通过php5.0 php5.2对比session环境变量参数。

相对路径的问题？
不是吧
