PhpStorm beginner's guide

There's a book?  wow cool.

The thing I found most useful was just start coding with it and see.

Then when you think you know everything, check:
HELP -> PRODUCTIVITY GUIDE

and it will give you a ton of things you didn't know about.

Also there are some video tutorials:

And useful text tutorials:

We really recommend sticking to our online tutorials.
