In a new blog post Jani Hartikainen shows how to create an abstract model that you can build on when you need to make a dynamic model for your framework application.

In a usual scenario involving models in PHP, you will have some repeating things: You will usually need getters and setters for the model's properties, you will need to be able to construct the model from an SQL query or such, and you'll also need to write SQL queries for the models.

He builds up the three different parts of the abstract model - the getters/setters, fleshing out the model by defining its properties from array values and creating some dynamic SQL (based on property names).
