number_format() problem

[micmac]

Hi all,
If i have:

<?
$subtotal = "1,124.00";
$shipping_cost = "1.50";

$grand_total = number_format($subtotal+$shipping_cost, 2, ".", ",");

echo "$grand_total";
?>

the $grand_total = $2.50 (this is obviously incorrect).
If i change the $subtotal to:

$subtotal = "1124.00";

the $grand_total = $1,125.50 (this is correct).
My question is what do i need to do in order to get the $grand_total to equal $1,125.50 in the first example?

Cheers,
micmac

I Think I See The Problem I Just Not Sure How To Fix It.

<?
$subtotal = "1,124.00"; 
$shipping_cost = "1.50"; 

$grand_total = number_format($subtotal+$shipping_cost, ".", ","); 

echo "$grand_total"; 
?> 

Try That.

I Think The 2 Threw Off The Output.

Thanks for the reply.
That didn't fix it, it will still require the value 2 for cent format.

It must have something to do with the "," in the $subtotal...just not sure.

Any other ideas?

You can remove ',' first, like this:

str_replace(",", "", $subtotal);

and then do the math.
