PHP5.4是公开发行的PHP程式最新版本。其执行速度和内存占用等相比PHP5.3而言有10%~30%的性能提升，所以笔者也一直想在实际环境中试运行PHP5.4(PHP5.4目前最新的版本为5.4.9)。
棘手的是与PHP5.2升级到PHP5.3有所不同的是，从5.3到5.4之间似乎变化不少，这也造成了笔者在将DEDECMS系统迁移到PHP5.4.x平台的时候出现了前台500错误后台直接空白的情况，当时也没有深究便换回PHP5.3了。
最近仔细查了下相关资料，发现主要是因为目前DEDECMS代码中使用了PHP5.4中弃用的一些函数，主要如下：
| 代码如下 | 复制代码 |
|
allow_call_time_pass_reference、define_syslog_variables、highlight.bg、register_globals、register_long_arrays、magic_quotes、safe_mode、zend.ze1_compatibility_mode、session.bug_compat42、session.bug_compat_warn、session_register以及 y2k_compliance |
|
其中造成DEDECMS5.7无法正常运行的函数便是session_register。
网上实测有效的方法有两种。
第一种方法申明将此函数废弃，在include/userlogin.class.php中加入如下代码：
| 代码如下 | 复制代码 |
|
function session_register() { return true; } |
|
第二种方法是该该页中的函数代码替换，被替换代码大致在287到308行之间：
| 代码如下 | 复制代码 |
|
@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; PutCookie(‘DedeUserID’, $this->userID, 3600 * 24, '/'); PutCookie(‘DedeLoginTime’, time(), 3600 * 24, '/'); |
|
替换为：
| 代码如下 | 复制代码 |
|
global $admincachefile,$adminstyle; if(empty($adminstyle)) $adminstyle = 'dedecms'; $_SESSION[$this->keepUserIDTag] = $this->keepUserIDTag; $_SESSION[$this->keepUserIDTag] = $this->userID; $_SESSION[$this->keepUserTypeTag] = $this->keepUserTypeTag; $_SESSION[$this->keepUserTypeTag] = $this->userType; $_SESSION[$this->keepUserChannelTag] = $this->keepUserChannelTag; $_SESSION[$this->keepUserChannelTag] = $this->userChannel; $_SESSION[$this->keepUserNameTag] = $this->keepUserNameTag; $_SESSION[$this->keepUserNameTag] = $this->userName; $_SESSION[$this->keepUserPurviewTag] = $this->keepUserPurviewTag; $_SESSION[$this->keepUserPurviewTag] = $this->userPurview; $_SESSION[$this->keepAdminStyleTag] = $this->keepAdminStyleTag; $_SESSION[$this->keepAdminStyleTag] = $adminstyle; PutCookie(‘DedeUserID’, $this->userID, 3600 * 24, '/'); PutCookie(‘DedeLoginTime’, time(), 3600 * 24, '/'); |
