A few days ago I asked in the Oso forum whether this source program, no one reply. Finally decided to transplant a function like this, thanks to the Netizen Keyes provides the Delphi source code for transplant. The method is called $TXT=BIG5TOGB ($txt).
(Note: the include "data_big5.php" in the source code; This file is an array, in Http://caocao.oso.com.cn/data_big5.zip, please edit the download to Oso, do a link, because this file I will be deleted in a few days. ）
