I'll throw in my hat for PHP. There will be many people who will tell you to avoid PHP and I would have agreed if it wasn't for the Laravel framework. Laravel 4 is really amazing, it carries the simplicity and power of Ruby on Rails over to the PHP world. As a framework it covers most of your typical newbie problems out of the box (e.g. plugging security holes and organising your code) and you'll end up doing things in one line of code that you previously did in 5. Laravel also basically forces you to write really reusable code by using their Eloquent ORM system.

Though my favourite great thing about Laravel is that the community IS ON FIRE (in a good way). You'll get a response to most questions on Stack Overflow or the Laravel Forum within a few hours or even less sometimes. The core dev team are friendly and really available to help out. I found that when people use Laravel they don't just use it, they love it and become almost strangely obsessed with it. It's also pretty new so you can safely assume that your skills will not go out of date really soon or anything.
