Note: php5.4 deletes the session_unregister function. The dedecms system was installed a few days ago. when security exits in the background, there is a blank background. Previously, only other functions were analyzed, and security was not paid much attention, after reading the security exit code, the dedecms system was installed a few days ago. when the security exits in the background, the background is blank. Previously, only other functions were analyzed, and security was not paid much attention, I read the security exit code and wrote it like this:
The code is as follows:
Function exitUser ()
{
ClearMyAddon ();
@ ($ This-> keepUserIDTag );
@ Session_unregister ($ this-> keepUserTypeTag );
@ Session_unregister ($ this-> keepUserChannelTag );
@ Session_unregister ($ this-> keepUserNameTag );
@ Session_unregister ($ this-> keepUserPurviewTag );
DropCookie ('deadmindir ');
DropCookie ('destuserid ');
DropCookie ('delogintime ');
$ _ SESSION = array ();
}
I was surprised to hear that I had written a blank article about logging on to the background after dede was installed. This reminds me of the possible php version. my php version is 5.4, check whether the new version is correct. in php5.4, the session_unregister function is deleted. the dededecms function is too outdated to support the latest php version, alas, it takes me time to analyze. In the background, replace this function with unset to solve the problem perfectly.
