Every time I need to sort a multi-dimensional array in PHP, I have to remind myself how to do it. It's not quite as quick and easy to look up as most things, so I'm going to blog a quick example. I've always felt like there must be a better way to do this, so please let me know if there is, and I'll update this post accordingly.

His method sorts a multi-dimensional array of user data using the array_multisort function together with a list of the usernames in each record. In the comments, people recommend using usort instead with a callback+closure combo that keeps things nice and clean.

When we have a multidimensional array we have to make some recursives function to parse it. A simple way to get the keys and the value of this type of array is to use the SPL library of PHP.

A code example is included, parsing through a recursive array to output each of the key/value pairs it contains (and using only about five or six lines of code to do it).

In our last exciting adventure (back in early November), we braved crocodiles, ravenous editors, most of the PHP statements, and beginning loops. In this edition we'll cover the final statement, the Switch, and discuss arrays. So sit back, order your R2D2 robot to bring you a cold, frosty Jolt Cola, and let's get cracking.

They start with a simple example of a switch statement (to echo out strings) and follow it with a detailed description of the different sorts of arrays - numeric indexed, associative and multidimensional versions.
