Ready, Set, Go
In this book, we are using PHP5.1.2 for our examples but for almost 99% of cases it
will run with PHP version 5x. We have MySQL 5 in our machine and Apache 2
as our web server. If you aren't familiar with configuring all these in your machine,
you can download pre configured WAMP or LAMP distributions like XAMPP
(http://apachefriends.org) or Apache2Triad (http://www.apache2triad.net).
You will find corresponding documentation for installation and customization on
each of these product's website.
A Little History of OOP in PHP
When PHP was developed, it did not implement OO features in itself. After PHP/FI,
when Zeev, Rasmus, and Andy rewrote the core and released PHP3, very basic OO
features were introduced. When PHP4 was released, OO features got matured with
huge performance improvement. But the PHP team rewrote the core engine again
to introduce completely new object models and released PHP5. Now there are two
versions of PHP being developed. Don't get confused by comparing PHP versions
with other languages. PHP5 doesn't mean it is the latest PHP version. As I said a
while ago, PHP4 and PHP5 are being released actively (though there will be no more
releases of PHP4 after December 2007).
