如何在 MySQL 中保留记录更新的历史记录?
我必须在 PHP 中创建一个代码，让我可以在 MySQL 数据库中保留记录更新的历史记录，以便我可以按日期查找旧版本.
I have to create a code in PHP that will allow me to keep the history of record updates in MySQL database so I can find by date an old revision.

I plan to use codeigniter for it's simplicity and I'm looking for idea about a framework or an opensource project that use the same approach to keep history of modifications in the database.
