One of my favorite parts about using WordPress for my blogs is getting to work with PHP code, which I find to be much easier to write/hack. For those that are shy around code, it really isn’t that difficult to get ahold of the basics of PHP, so WordPress is the right place for you.
One great area to start is learning how the WordPress loop works. This is a basic function of blogging used to display the most recent X number of posts on your blog’s homepage (for traditional blogs). Rather than go into to much detail here, I’d like to point you towards a new post by Themelab which is designed to be the Utlimate Guide to the WordPress loop.
This post definitely lives up to its name and goes beyond just showing you how to do something. It actually explains how and why it works, and includes screenshots with many of the examples. If you have any interest in learning about the WordPress loop you may want to read through this post and/or bookmark it for future reference.
