Part 1 - Refresher

Here's what you should have covered in the far-better Code Acadamy lessons. I'll use these liberally from here on out so be sure you know what these all are. ALSO I've spent 0 time making the output "look good". This is essentially outputting HTML that you would normally only see at Geocities, since the focus here is on PHP code, and not HTML or CSS.

Click that shitty "SHOW SOURCE!" button at the bottom of every page to look at the entire lesson's code in full. I've forced you to look at this page's source already.

You should be familiar with the following by now:

AND (some of) THE REST:
count(), array_push(), array_shift(), rsort(), ksort(), usort()... blah blah blah (no one really memorizes these extensively for a long time... use google A LOT to find what you need)

BUT WAIT THERE'S MORE!!!

Up next, we'll cover creating your own functions. Click this hideous button to continue:
