PHP Deprecated: Function ereg_replace() is deprecated in 的解决方法

这个问题是因为你用的php版本过高，在php5.3中，正则函数ereg_replace已经废弃，而dedecms还继续用，有两个方案可以解决以上问题:

1.把php版本换到v5.3下。

2.继续使用v5.3,修改php.ini文件

;extension=php_mbstring.dll

改为

extension=php_mbstring.dll

;mbstring.func_overload=0

修改为:

mbstring.func_overload=7

或者使用其他的函数:

define('DEDEADMIN', ereg_replace("[/\\]{1,}",'/', dirname(__FILE__)));

//改为

define('DEDEADMIN', preg_replace("/[\/\\\\]{1,}/",'/', dirname(__FILE__)));

注:因为preg_replace比ereg_replace的执行速度快，PHP推荐使用preg_replace。
