Adding elements in two different arrays

[Anon]

Dear All,
Consider that I have two arrays like the following that contains same type of elements like this:
$ar1=array("12.01","23.45");
and $ar2=array("34.55","55.65");
Can I create a new array by adding the elements of the two arrays?
Means the result should must be like this:
$ar3=array("46.56","79.10");
Anybody can quench my desire? I need this soon.
Thanking you,
regards,
Indrajit.

<?
foreach ($ar1 as $key => $value) {
$sum = $value + $ar2[$key];
$ar3[] = $sum;
}
?>

The above code assumes that both arrays have the same number of indecies and have numerically ordered keys (as your example does).
