混合PDO和MySQL函数？

Question

On the existing system its use old MySQL functions.. I would like to replace it all to PDO but it would take a long time and a lot of testing.

Is it possible to mix PDO and MySQL Functions on the existing system? For example new pages/php files will use PDO... All the old files will still use old MySQL for time being and will be replaced slowly as system will continue to update..

Answer 1

Yes, it is perfectly fine to use both at the same time. Keep in mind, though, that you would need a seperate connection for either type and beware of the implications that arise from such an approach.
