Not Telling
Not sure which types of collision detection would be most useful to you. If you're doing 2d tile platformer these might help:
Types of tile based collision methods:

Pixel perfect collision detection:

Here you can find rectangle-based collision detection source code - also links to pixel-collision and others:

I'm thinking rectangle-rectangle collision detection works for most things (but may want to try bounding-circle [radius-overlap] for some things)
