I have dabbled in PHP for a number of years, really just doing a tiny bit for one of my websites and then moving on, never investing much time in the language.<p>Now that has to change, I really need a book to sit down with that will teach me the core basics without over complicating things, and then allow me to move on to harder books.<p>Would also like to know if there are actual online study groups/classes where I can learn from my peers?
