from what I know, and you should take my word lightly since I don't have experience with this:
ruby (on rails) is what you use when you want a backend for a small site fast.
python (flask) is what you use when you want a small to medium site with more control than ruby
python (django) is what you use when you want full control for a big site
php... not sure. but it's an ugly poorly designed language. however, it's also very widely used.
I hope some other can pitch in and give more accurate info

@Ahri...looks like a good answer to me. The distinctions of small/medium/large implies capabilities, I like Python and I really don't feel like defending PHP.
@akash: Some reading, probably just skim:
