I've begun to learn PHP again, have tried a few times before but can't seem to get the same hang of it like HTML and CSS.
Well, I can do the very basics, but would like to start using some functions and such. Can you recommend some good functions for a beginner, that are nice to know of? I know of some already, namely:
include() and require()
mail() - don't want to make a mailform though as I have one that is fully working
I was hoping someone could recommend some new ones to learn.
