In a sort of "remind himself later" kind of post, Chris Shiflett has shared a quick example of a common task PHP developers face sorting a multi-dimensional array.
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.
