> I'm looking to build something new, and need a refresher on the exciting opportunities at the moment. So... what's good now?
That depends. What are you trying to accomplish?
> PHP sucks now right? Did Python replace that? And what about IOS? Is there more opportunity there, or is Android "where it's at" these days?
Same answer -- it depends on what your goals are. You just asked a question so general that it mixed platforms (Android, IOS) with languages (Python, PHP), so your inquiry is too general to be meaningfully answered.
> PHP sucks now right? Did Python replace that?
There's really no comparison -- PHP and Python address completely different purposes. It's like asking which is better -- a car or a typewriter.
> In other words, what's cool these days?
Technology isn't a fashion show. Well, anyway, it shouldn't be.
