Just because you refer to resources once in a while doesn't make you an idiot. I'm pretty sure that everyone who has posted in this thread refers to resources at least once a month, if not way, way more than that. An expert, in my opinion, is someone, who given the tools, can solve almost any problem.
For example, drawmack helped me with something I was having trouble with. The code he came up with was simply brilliant. Did he have to refer to the manual while he was making it? Probably. If I'm wrong drawmack, just tell me.
I'm still relatively new to PHP, and I'm nowhere near an expert, but the manual is still my best friend (when I'm on the computer).
