1. If you're serious about OO, learn what they mean.
2. http://nl3.php.net/manual/en/language.oop5.visibility.php It was
introduced in PHP in version 5, in 4 it will not work. From the manual:
"Note: The PHP 4 method of declaring a variable with the var keyword is no
longer valid for PHP 5 objects. For compatibility a variable declared in php
will be assumed with public visibility, and a E_STRICT warning will be
issued."

You can:
http://nl3.php.net/manual/en/function.serialize.php
http://nl3.php.net/manual/en/language.oop5.autoload.php
You might want to ask yourself wether this is really needed, and why exactly
some simple variables aren't enough.

Just keep in mind OO isn't neccesarily better, and www.php.net is a great
source where you would have found answers to this questions very quickly. Be
sure to read the user contributed notes.
