Fix SQL garbled characters in normal database files on the MySQL page

MySQL page normal database file SQL garbled
If your database is originally gbk encoded, save the following code as a PHP file. Remember to fill in the following database name and password<? Php
Define ('db _ name', 'putyourdbnamehere '); // Database NAME
Define ('db _ user', 'usernamehere '); // MySQL USER name
Define ('db _ password', 'yourpasswordhere '); // PASSWORD
Define ('db _ host', 'localhost'); // you do not need to modify this item.Function gbk_DB_Converter_DoIt (){
