Chapter 1. What's New in PHP5?
So what's the big deal about PHP5? If you're experienced with PHP4, you probably know about object-oriented programming and the way this was handled with PHP4. If you're unfamiliar with PHP, but you're familiar with other programming languages, you'll probably find PHP5's implementation of object-oriented principles familiar. Luckily, things have become a lot easier with the release of PHP5. However, there are other improvements and changes, such as more configuration options in php.ini and a host of new array-related and other functions, besides just "better object-oriented programming" handling. This chapter outlines these changes for you.
