Code help

[Maxpphire]

I'm looking at code so that way maybe I can make an updateable m3u file for an online radio station for video game/anime music (and occasional special podcasts). Trying to learn shit on my own by looking at code at a couple of sites that do a similar thing I'm hoping to actually be able to pull off a similar thing.

(I wanna make a request system, you sign and log in, can request 5 songs at a time (one you request plays, you can request another song, songs that have already been requested and haven't played yet can't be requested again) and can post in forums to make suggestions and other things of that nature. Still working out the kinks buuuuuut, if you wanna help me and/or point me to the right places to learn, please do so)

Also if you do point me in a direction to do into and learn, please let it not be Javascript doing math, I've seen enough of that shit to last a lifetime.
