Today I changed the system to windows server 2008 r2 and upgraded the PHP environment to PHP5.5 version. There was no problem at all when testing PHPinfo, but when logging in Dede shows a 500 error in the background. How to solve this? Baidu found out that dede does not support PHP5.3, PHP5.4 and above. The main reason is that the version of php5.4 has been abolished. session_registerFunction
can be used For example, $_SESSION[$this->keepUserIDTag] = $this->userID;

The complete code is processed in this way as follows
First open the include/userlogin.class.php file, at line 287 The original content of line 308 is as follows:

The code is as follows:

@session_register($this->keepUserIDTag); 
$_SESSION[$this->keepUserIDTag] = $this->userID; 
@session_register($this->keepUserTypeTag); 
$_SESSION[$this->keepUserTypeTag] = $this->userType; 
@session_register($this->keepUserChannelTag); 
$_SESSION[$this->keepUserChannelTag] = $this->userChannel; 
@session_register($this->keepUserNameTag); 
$_SESSION[$this->keepUserNameTag] = $this->userName; 
@session_register($this->keepUserPurviewTag); 
$_SESSION[$this->keepUserPurviewTag] = $this->userPurview; 
@session_register($this->keepAdminStyleTag); 
$_SESSION[$this->keepAdminStyleTag] = $adminstyle; 
Put
Cookie
(‘DedeUserID’, $this->userID, 3600 * 24, ‘/’); 
PutCookie(‘DedeLogin
Time
’, time(), 3600 * 24, ‘/’);

is replaced with

The code is as follows:

if
(empty($adminstyle)) $adminstyle = ‘dedecms’; 
//@session_register($this->keepUserIDTag); 
$_SESSION[$this->keepUserIDTag] = $this->keepUserIDTag; 
$_SESSION[$this->keepUserIDTag] = $this->userID; 
//@session_register($this->keepUserTypeTag); 
$_SESSION[$this->keepUserTypeTag] = $this->keepUserTypeTag; 
$_SESSION[$this->keepUserTypeTag] = $this->userType; 
// @session_register($this->keepUserChannelTag); 
$_SESSION[$this->keepUserChannelTag] = $this->keepUserChannelTag; 
$_SESSION[$this->keepUserChannelTag] = $this->userChannel; 
//@session_register($this->keepUserNameTag); 
$_SESSION[$this->keepUserNameTag] = $this->keepUserNameTag; 
$_SESSION[$this->keepUserNameTag] = $this->userName; 
//@session_register($this->keepUserPurviewTag); 
$_SESSION[$this->keepUserPurviewTag] = $this->keepUserPurviewTag; 
$_SESSION[$this->keepUserPurviewTag] = $this->userPurview; 
// @session_register($this->keepAdminStyleTag); 
$_SESSION[$this->keepAdminStyleTag] = $this->keepAdminStyleTag; 
$_SESSION[$this->keepAdminStyleTag] = $adminstyle;
