How to increase my “advanced” knowledge of PHP further? (quickly) [closed]

Answer 1

Maybe you should look into frameworks again, I would suggest having a look at the Zend Framework, because it's more like a library of components you can use as you see fit, and doesn't really impose a rigid structure you have to follow (like some other frameworks do), though it does suggest a (quite sane imho) project layout. A good starting point would be Surviving the deep end.

Things you haven't mentioned yet, and that could prove useful to know (especially in larger projects) :

• OOP with PHP (design patterns)
• Unit testing (PHPUnit, SimpleTest, ...)
• ORM (Propel, Doctrine)

Answer 2

Simple: do it. Needs will make you learn. Find a way to get involved in increasingly advanced projects, be it commercial or open source. There is no other way you can really learn something.

Answer 3

Read other people's code. You have your own library now, yet you might get some enlightenment when reading the source of other applications. Then ask yourself the 'why's. Be the blog writer, instead of the reader. Also, emphasize more on the programmer than the language. Rather look at solutions that already solve a problem and try to replicate them with your own knowledge. Good luck and have a lot of fun!
