Shawn Stratton has posted the first part of his series looking at "Code Readability". This part focuses on something that is often woefully forgotten by many developers - proper code commenting.

The simplicity of PHP can sometimes be overwhelming, with so many different ways and approaches to creating solutions for our problems we sometimes lose the ability to think past the current problem and into the future. [...] Today I'm going to try to address some quick ideas that most of you will already be familiar with, things that will aide in the general readability of code for future generations.

He looks at the difference between useful and non-useful comments: DocBlocks, putting them near decisions, listing array parameters, recording TODOs and how it can all help you generate API documentation quickly and easily.
