PDO：动态检测数据库驱动程序

Question

I'm creating my own CMS, part of this is making sure it is interoperable with different database types. PDO is therefore my default choice, my question is:

Is there any way to dynamically detect and set the database type in a PDO connection class?

As far as i can see there isn't so i was thinking just doing a bunch of try/catch on different database types then writing the one that doesn't throw an exception to a config file.

Answer 1

Although PHP has extension_loaded() function, as it was noted in the comments, multiple databases support is not that easy.

Your question is a typical example of premature engineering. You don't have your CMS yet, you don't have support for even one database, but your only concern is how to detect it.
