PHP Random Problem - Pick Your Poison Game

firedealer · August 2, 2010

I developed this game and I couldn't figure how to make random only on available shot glasses but it would still random with unavailable shot glasses. I simple give up. I plan to share this php once I nailed it down but apparently, not successful. Now, I'm share with you anyway. If you can solve the problem and please let us know!

Thanks!

I need to study $_SESSION more, I suspect $_SESSION is most important part for almost any project.

The in_array() function is new to me, there are so many functions!

Again, thanks.
