DEDECMS在PHP5.4不能正常运行的解决方法

分享时间:2018-06-12 9712 热度℃
本文实例讲述了DEDECMS在PHP5.4不能正常运行的解决方法。分享给大家供大家参考。具体分析如下:
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:
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如下两种:
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:

复制代码
代码如下:

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
代码如下:

@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, '/');


替换为如下代码:

复制代码
代码如下:

global $admincachefile,$adminstyle;
if(emptyempty($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, '/');


希望本文所述对大家的dedecms建站有所帮助。
