今天把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
if (!isset($_SESSION[$this->keepUserIDTag]))
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;
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();
