I've just started back with PHP as well, and nice things I've seen that didn't exist when I last did PHP in 2006 are:
Composer - a dependency manager that's a lot like Bundler.
Pimple - a dependency injection framework.
Klein - a routing library that's much nicer than handling routes in Apache or working with requests directly.
As for an editor, I've just been using Eclipse with the PHP development tools. I'm sure there is a better tool out there, this was just the first thing I grabbed.
