Tuts? Where to find them.

Hello,
I would like to know where I could possibly find lessons about HTML/PHP/CSS to make my website.
I have already bought the site and so on,I just need to make the "touch" of this site which is the surface. I heard that making a site isn't that hard,I would like to make a full forum,So ! Tell me,whats the best for my case.
Thank you in advance.
