Not sure of your level of knowledge, but the LAMP stack is a good place to start.

For the scripting language, you won't go far wrong with Ruby on Rails (pleasure to use) instead of PHP (potentially heartbreaking).

Also, it's considered good etiquette to have your basic research done before posting help requests on forums, saying things like "save the effort of looking them all up" smacks of laziness, fyi. It's not like a Google search can be compared to running a marathon or something!

Hope that helps.
