total from an object

[Anon]

Hi can anyone help with this I would like to show a total at the end of the loop like a grand total.
Thanks

<?php

class Calculation2
{
// function for var
function QuoteEngine($var,$qty,$spec){

	if($var){

		global $total;

		$this->varX = round($qty / $var,2);
		$result = mysql_query("SELECT * FROM Specs
                       WHERE Hours >= \"$this->varX \"
                    ORDER BY Hours ASC
                     LIMIT 1");
		$row = mysql_fetch_array($result);{
			$this->varHr=$row[HandworkHr];
		}
		$this->varam=$this->varX * $this->varHr;
		$this->varM=round(($this->varam/$qty)*1000,2);

		echo"amount $this->varam <br>";



		$total= $this->varam; 

		return ($total);

	}
}

}

//other page
//get array from select from equipment table

include("../Include/dblib.inc");

$spec=array(HeidHr,HeidHr,GluerHr);
$var=array("2000","3000","4000");
$qty=array("3000","4000");

$obj1=new Calculation2();

	for($i=0;$i<count($qty);$i++)
{
		for($j=0;$j<count($spec);$j++)
{
	$obj1->QuoteEngine("$var[$j]","$qty[$i]","$spec[$j]");
		$total += $total[$j]; 


}
}
echo"Total $total <br>";

Just create a new variable that is the sum of all your other variables.

$GrandTotal = ($SubTotal1 + $SubTotal2);
echo "$GrandTotal"

or something like that.

Thanks for your response but each loop through comes back as the same variable name.How do I keep adding to the previous.
