You're serious? Like, really serious? The kind of serious that will cause you to be within the 20% of doers and not the 80% of talkers? THAT kind of serious?
Oh, you are. Cool!
Well then I would suggest that you get a good programming book: the latest edition of PHP and MySQL Web Development.
Do each exercise. As you spend your mornings drinking coffee and shunning human contact while making hypothetical auto-parts e-commerce sites (from the examples in the book) you will begin to grok how database-driven web sites are made. Your mind will expand (yes you will actually feel it! it's like a wild acid trip, man!) and when you walk through Barnes & Noble or the university library the nerdy girls' heads will turn...and they won't quite know why they're so attracted to you. But you'll know. For you will now be one of them. (Mind you, these will be actual nerdy girls - not hot chicks who wear glasses.)
Next get the Web Bots book by Mike Schrenk. Read that one as well. Do the exercises in that book also.
About three weeks will have passed by now, and assuming you spend a few hours daily immersed in the world of functions, variables, and such things and have made it through these volumes...you will have gained an understanding of the Way it All Works Together.
As you try to solve problems in everyday life with code, you will search for other people's code (people who have already invented that particular wheel) and you will learn from them. The coding powers will be strong with this one. (Meaning you.)
Then, you'll get a programming job in a few months...or a year. Then we won't see too much of you here at BHW - you'll be too "busy" for us. Making money and stuff. Going out with the nerdy girls. Being around your new friends who talk about scripts and whatever.
We'll say: "What changed, man? We liked you the way you used to be...and then you went and became a programmer." Oh, sorry - a coder. Whatever. "Forget it," people on BHW will say. "We used to be cool. And then you changed."
All because you got that programming book.
But yeah, if you're serious you should totally do what I just said.
