I want to learn PHP so I ordered a book about it called "PHP 6 and MySQL 5 for Dynamic Web Sites: Visual QuickPro Guide"
I stumbled upon the php.net website and found out the latest thing released was PHP 5.3.2
The describtion of the book says that "[...] 20% or so of the material requires version 6 of PHP."
DID I SCREW UP AND SHOULD I CANCEL MY ORDER?!
Ps.: I don't know if this question is too argumentative...
