I’m a little interested into delving into PHP, and picked up a book from my library to learn more about it.
However, the book covers PHP4 (Library doesn’t keep up with the times…), and I know PHP5 is the current standard.
Will a PHP4 book teach me things that are depreciated, useless, or just plain wrong? Or could I learn sufficiently enough to be able to jump into PHP5 with no problems?
PHP4 is DEAD, you’ll be filling your head with useless things specific to an old, dead language. Here’s a free book that should cover 5 and up: http://www.tuxradar.com/practicalphp
Of course you can gather general programming tips from it, but it would be better if you had a more modern book to learn from.
