If you're a PHP programmer who wants to learn how to implement the active record pattern within a MySQL abstraction class to make your database-driven applications more robust and maintainable, then look no further.

It will be charged with executing conditional SELECT statements via a modified version of the active record pattern.

After reviewing the CRUD functionality from the previous articles, they add in the new method - a fetchWhere function that allows the user to submit a table name and the parameters to add to the where clause as an array. Some sample code is included.
