I have some expirence with C++, lots of experience with HTML (not even worth bragging about html though :P) which seems to have some relation to PhP (C++ atleast). I installed WAMP after many failed tries of installing php/apache/MySql. I havent written any code yet, but where do I get it compiled, before putting it online? Can I see my php on an unlaunched site? (I still need to compile it somewhere though, right? Or is it like html...? With variables?) This has probably been asked many times, but I couldent find it anywhere, all the tutorials I found went from installing your resources to writing php, with no stop to say how to compile, veiw it :/. (Sorry for being a noob :P)
