I would consider myself to be at an intermediate level of php coding, I can do all the basic stuff in php, connecting to database, includes, functions, arrays, etc. However I would really like to elevate my knowledge of the language to a more advanced level.
Does anyone have any suggestions for books or classes online I could take a look at? Or should I just focus on perfecting the skills I already have?
I have been looking at some of the books on amazon but they seem to just cover stuff I already know.
Any suggestions would be greatly appreciated.
