I am reluctant to do PHP because of time contraints. I am working on this stuff after work, and at some point I would like to actually be able to build something. Anything. When someone says do PHP, my visceral reaction is no.

However, if the experts here think that PHP would be a worthwhile detour even though I plan to go with Rails, then I'll go with that. I guess I'd just like some assurance that I can pick up the basics this way and that I can do so in a reasonable amount of time.

Yes, I know patience is a virtue, but I just want to make sure that my time is spent as productively as possible. I do very much appreciate the advice from everyone.
