General Programming Literature

[Shinigami-Sama]

So I'm trying learn a bit more about programming, I'm pretty decent in PHP, and not bad in bourne, though I'm a little rusty now

What I'm looking for in general is the making of a good modular, extensible system
does any one have an recommended reading?

I'd like to stay away from OO, I'm not a fan, but thats probably due to being taught OO poorly...

If you want modular/extensible, OO is your friend, not your enemy.

If you want easy to program in without OO, try Python.

If you want easy OO, use Java.
