I was kind a skeptic about moving from heavy weight IDE(eclipse like) to Sublime. But damn sublime is damn quick. Sublime is not a fork of Vim. With few plugins you can keep your old flow. With another few more you can optimize it.
I did this and two months ago and still my eclipse icon is covered with dust.

A: Install PHPUnit
Q: Want to write with PHP-PSR-2?
A: Install PHP Code Sniffer
