Weak PHP Tic-Tak-Toe

Posted: Tue Jul 25, 2006 8:16 pm

So I basically finished the website at my work in about a week or so, so on the day that they were transitioning me to a new job, I had some free time to goof off. [what a craptastic sentence... 3 so's in one] I thought to myself, what can I do in about an hour. I decided to make an attempt at Tic-Tac-Toe in PHP because I thought it would be fast and easy... It ended up taking a wee bit longer. Yeah.... it ended up being like a billion lines of code. And the AI blows because I got bored half way through and just said the heck with it.

I thought it would be humorous to send all the game info through the URL... so I did... But I don't know why I thought that was funny at the time.

Anywho, check it out: Tic-Tak-Toe

This be the code. (although there seems to be strange amonts of white space towards the bottom, must be the text editor I used)

Code: Select all
