I thought of something that would be both, easy to implement and easy to use. What I finally came up with is tightly coupled to my new url system that I'm using, so make sure to check it out in case you've missed it.

The basic idea of the system is that the URL of the page (made up partly of the title) would be the unique identifier for the page. For example, "[page 12]" would be expanded out to "/pages/12:my-title". Felix takes this idea and runs with it, showing how to implement it in a CakePHP project inside of a Model and a Component. The sample usage code is, of course, also included in the post.

All code is tested at some point-perhaps during its implementation, during a dedicated testing phase, or when it goes live. Any developer who has launched broken code live knows that it is easier to test and debug code during development than after it goes into production.

Unit testing helps with finding these problems before they get into the hands of live users. The tutorial gives you a basic overview of how to work with this handy tool, specifically with the PHPUnit package. They help you write a simple test, expand on this base with more elaborate tests, and how to package your tests right in with your libraries to make installation/packaging simpler.
