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.
So there are eight questions to ask yourself:
Q: Want to install anything?
A: Install Package Control
Q: Want to avoid typos and syntax errors?
A: Install SublimeLint
Q: Want to remember about documentation
A: Install DocBlockr
Q: Want to write html & twig faster?
A: Install Emmet
Q: Want to update composer from your sidebar?
A: Install Composer
Q: Want to run your PHPUnit from your editor?
A: Install PHPUnit
Q: Want to write with PHP-PSR-2?
A: Install PHP Code Sniffer
Q: Want to do more with less code?
A: Install following packages:
And the final one that you need to answer yourself.
Do you dare to move to sublime2?
Buy the freaking license.
