Traditional conversion class_PHP

This is a traditional and traditional class with a class package. Two other table types are required: 1.www.jerry.com.twphpbig5.map2.www.jerry.com. twphpgb. map. The program is as follows: CCharset. php3? Programmer: MagicJerryfu: this is a class with a strong traditional programming class,
Two other table partitions are required:
1. http://www.jerry.com.tw/php/big5.map
2. http://www.jerry.com.tw/php/gb.map
The program is as follows: CCharset. php3
