i currently am planning to start a large scale framework that is mainly for enterprise development with php.
The question i have contains to the model layers and what is a proven better and overall faster option for a database abstraction layer PDO? , ADOdb? in a large scale application sense?.
this will be used with a mapper pattern that will control and manag various aspects of communicating with a relational database such as mysql , mysqli , postgres, etc... and so on...
Please i'am look for the most tested and fasted solution that aswell can scale well.
