I personally prefer PHP, having used both. I'm not saying that Ruby is better or PHP is better, it really depends on your ability with the two, but from what I have found in the past, PHP has been easier to scale and has performed well, it is also more widely hosted, though this is really irrelevant as there are still plenty of ruby hosts. Support for PHP is generally better as it has a larger user-base but generally Google is your friend either way. You should make the decision based on personal preferences, for instance, I find Ruby much more fun to write, but I can't stand debugging it, whereas I have used PHP for so long that now, those stupidly bad error messages are actually a native language to me.
