We know there are LOTS of tutorials on youtube and everywhere for beginners, but what about SSr. and Sr. developers? where do you learn new tricks about PHP? do you have specific sites/blogs to read or just dig into google when you need it?

In my case, I think Symfonycasts is pretty good, but I wish they had more advanced content, like egghead but for PHP.
Here is my list.
phparch’s magazine.

Domain-Driven Design in PHP (leanpub.com). MUST READ.
PHP OOP Way (leanpub.com). MUST READ.
Lynda (they have pretty good advanced courses for PHP); Start with “Standard PHP Library” it’s a great course.

PHP Design Patterns (Lynda).
PHP’s official documentation.
PHP’s website is brilliant, I just use that
