php5.3 does not support Ereg, ereg_replace, and other function issues, such as: Deprecated:function Ereg () is Deprecated

In php5.3, the regular function ereg_replace has been discarded, and dedecms continues to be used. There are two solutions to solve the above problems:

1, change the PHP version to v5.3.

2, continue to use v5.3, modify the php.ini file

; Extension=php_mbstring.dll

Switch

Extension=php_mbstring.dll

; mbstring.func_overload = 0

Modified to:

Mbstring.func_overload = 7

Or use a different function:

Define (' Dedeadmin ', ereg_replace ("[/\\]{1,}", '/', dirname (__file__)));
Switch
Define (' Dedeadmin ', Preg_replace ("/[\/\\\\]{1,}/", '/', dirname (__file__)));

Note: Since preg_replace executes faster than Ereg_replace, PHP recommends using Preg_replace.
