First of all, it's spelled career not carrier.

PHP vs Ruby is not going to make a big difference. What matters is how you good you are.

Listen to your parents and go to college. If you love working with computers so much, a Computer Science degree will be fun. There's a lot more stuff to learn in CS than merely becoming an expert RubyonRails programmer. Do your web development stuff while you're studying and if you do become the next Zuckerberg, drop out then!
