Definitely.
I've learned easily enough via the Internet and all classes near me are horribly over priced. ($800 for 20 hrs... that works to $40/hr, with 30 students per class is $1200/hr they're making off us!)
A good suggestion is get a nice PHP tool that helps you develop, it's worth it's weight in gold. Especially if it has a 'beautify' button!
I would recommend
www.phpdesigner.dk - It has a trial if you need to test it.
