You are at one of the premier sites for this very thing 😉
PHPBuilder.com has some great articles, code snippets and gathering of documentation... And all of that is before you ever even enter the forums... In the forums, you get a great blend of how a lot of GURU's (including authors of PHP reference books) write their code. You get a lot of variations on how to do things, and you get great real world applications of the code.
