learning to right objects

I am trying to change some of my functions in to classes and objects. I have been checking out the php.net and google and still not grasping the concept. here is my example all I am trying to do is print 2 numbers to the browser that are randomly generated from dieRolls. Thanks in advance -Blake class dieRolls{

       function dieRolls($die){
               $num = rand(1, $die);
               $this->num;
       }

}

$num1 = new dieRolls("6"); $num2 = new dieRolls("8"); $bar1 = $num1->bar1; $bar2 = $num2->bar2; echo"Hi<br>\n"; echo"$bar1<br>\n"; echo"$bar2<br>\n"; -- +-----------------+-----------------+----------------+ | Blake Schroeder | Owner/Developer | lhwd.net | +--(http://www.lhwd.net)------------+--/ \--+
