解决更换PHP5.4以上版本后Dedecms后台登录空白问题的方法,php5.4dedecms

把PHP的版本从5.2.14升到了5.4.15,升级完后dedecms后台却打开空白,检查了各种权限和文件,都没有问题,找来找去,原来是PHP版本函数的问题,它是用session_register来注册一个session变量,但是在php5.4以上中已经移除了这个功能
解决办法:
找到include/userlogin.class.php,里面有一个keepuser()函数,它是用session_register来注册一个session变量,但是在php5.4中已经移除了这个功能,见官网介绍:

如果使用的该php版本肯定会出错的,不过我们可以修改下代码:
把@session_register($this->keepUserIDTag); 注释掉,然后改为
if (!isset($_SESSION[$this->keepUserIDTag]))
一共有六个,全部改为下面这样:

if (!isset($_SESSION[$this->keepUserIDTag])) 
//@session_register($this->keepUserIDTag); 
 
$_SESSION[$this->keepUserIDTag] = $this->userID; 
 
if (!isset($_SESSION[$this->keepUserTypeTag])) 
//@session_register($this->keepUserTypeTag); 
 
$_SESSION[$this->keepUserTypeTag] = $this->userType; 
 
if (!isset($_SESSION[$this->keepUserChannelTag])) 
//@session_register($this->keepUserChannelTag); 
 
$_SESSION[$this->keepUserChannelTag] = $this->userChannel; 
 
if (!isset($_SESSION[$this->keepUserNameTag])) 
//@session_register($this->keepUserNameTag); 
 
$_SESSION[$this->keepUserNameTag] = $this->userName; 
 
if (!isset($_SESSION[$this->keepUserPurviewTag])) 
//@session_register($this->keepUserPurviewTag); 
 
$_SESSION[$this->keepUserPurviewTag] = $this->userPurview; 
 
if (!isset($_SESSION[$this->keepAdminStyleTag])) 
//@session_register($this->keepAdminStyleTag); 
 
$_SESSION[$this->keepAdminStyleTag] = $adminstyle; 
Copy after login

重新进入后台登录,就可以正常跳转到管理页面了。
因为对PHP并不熟,网上一般都说是data/common.inc.php文件编码的问题,把编码要改为无BOM格式文件保存,居然没有说是php5.4版本的问题
另外一种方法:
在include/helpers/util.helper.php末尾加入以下代码

function fix_session_register(){  
  function session_register(){  
    $args = func_get_args();  
    foreach ($args as $key){  
      $_SESSION[$key]=$GLOBALS[$key];  
    }  
  }  
  function session_is_registered($key){  
    return isset($_SESSION[$key]);  
  }  
  function session_unregister($key){  
    unset($_SESSION[$key]);  
  }  
}  
if (!function_exists('session_register')) fix_session_register(); 
Copy after login

这样php5.4下dedecms就能正常使用了,希望本文分享的两种方法都可以帮助大家顺利解决问题。
