I’ve doing a little reading about the WordPress loop. The WordPress loop is where all the main work get’s done in publishing the articles of the blog. Loops and iteration constructs are very common in many (all?) programming languages, and that is why you see things like “do while” or while, “for x = 1 to z”, or “foreach x in z” in many scripting languages.

The whole idea with Open Source software is that you can modify it, refactor it, change it to be anything you want. However, it is a good idea to start with some very small changes, and it’s really good to begin by reading a few articles about the code, and read the actual source code before you start making any changes.

Anyway, two recent articles, I have have found helpful are: The Ultimate Guide to the WordPress Loop and another called Global Variables and the WordPress Loop.
