You won't find any free named hosts with php/mysql, rarely.. possible but I doubt it. Only possibility is to get a friend that has space which his host supports php/mysql and he is willing to help you.
3 Dollars a month = 3x12 = $36. I'm 15 and make 300 dollars every other week. You said you were 17, I don't see how this is a problem for you.
Maybe if I find it worth my time, I could give you space, but right now you've proven yourself as a nuisance.
