Description: While no function reference can top the ease of use and simplicity of php.net/$function_name, some manage to hold their own. This isn't just another regurgitation of the downloadable help system, this book actually manages to give you usable examples along with function explanations you can wrap your head around. This is not a book for those just beginning PHP, and I pity anyone who write an application using only this book. You better have some preliminary knowledge of PHP before picking up this book, but beyond that it's probably one of the best reference books available, and small too!
