A few days ago, I asked on the oso forum if there was such a source program, but no one responded. I finally made up my mind to transplant such a function. Thanks to netizen Keyes for providing the Delphi source code for transplantation. The calling method is $txt=big5togb($txt).
(Note: include "data_big5.php" in the source code; this file is an array at http://caocao.oso.com.cn/data_big5.zip. Please edit and download it to oso to make an link, because I will delete this file in a few days.)
