How do you declare Vars in PHP? -I know it's not necessary, but I still want to know

["Jon M." <dsak8330225@xxxxxxxxx>]

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.
