DevShed steps into the final part of their series looking at Command objects in PHP5 with this new tutorial just posted - "Using Self-Saving Objects with Command Objects in PHP 5".

I'm going to extend the creation and use of command objects to use the pattern in a more helpful fashion. Essentially, I'm going to explain how to utilize command classes for defining and handling self-saving objects, that is objects capable of storing a copy of themselves on a database, text file, etc.

They start by defining the core modules and classes for the creation of the objects. They build the other functionality on top of that, creating the save and load mechanisms. The wrap things up and add a few more small bits of functionality before giving a real-life example of the pattern and code in action.
