I work with PHP everyday at my job. Is it my favorite language? No. Are we in a position like others (e.g., Facebook) where we have a ton of code and infrastructure build around PHP? Yes. Do I love my company? Yes. We have strict coding standards and high requirements for code quality. Gradually, we are changing out some of our code for Python, where it makes sense, but I doubt we'll re-write our entire applications anytime soon.

We've taken our two-claw hammer and done some fairly nice work with it.
