One of the reasons I LOVE WordPress is that it makes some mundane programming chores very easy, particularly working with the database. WP uses a modified version of the ezSQL to interact with the database, and provides a number of data cleansing functions, both of which are huge time savers. One other thing that WP [...]

PHP – Sort a Multi-dimensional Array by Value for a Key
Here’s a problem I’ve run into a time or two with sorting arrays. I had a multi-dimension array that I needed to sort on a the values for a specific key (“name” in this case). This array is similar to what you would get back from a mysql database query when you use ARRAY_A to [...]

I ran into a problem with a SQL JOIN in Codeigniter’s ActiveRecord class. This post will help you get past that, but first a little intro to frameworks.
