I just found a place here:
http://us2.php.net/manual/en/language.oop.php
That has this example:
/* This is how it should be done. */
class Cart {
var $todays_date;
var $name;
var $owner;
var $items = array("VCR", "TV");
function Cart() {
$this->todays_date = date("Y-m-d");
$this->name = $GLOBALS['firstname'];
/* etc. . . */
}
}
It appears that they are declaring vars like this:
var $todays_date;
Is this something you can only do inside a class???

I think you can do like this inside a class
var $variableName;

check out http://www.php.net/manual/en/language.variables.php

when u use OO concepts, then you can use var. other wise its not neccessary.
