$aryTemp=("A"=>Array(1,5,3),
"B"=>Array(15,20,52))

sum_subarrays_by_key($aryTemp, $aryTemp[$key]

function sum_subarrays_by_key($aryTemp, $key)
sum=0;
foreach($aryTemp as $sub_array){

$sum += $sub_array[$key];}
}
return $sum:
}

What I want to know how to do is change the above script to make it
add a 3rd array of arrays?
c=> Array(C1=> Array(17,4,8), C2=>Array(1,4,10))

thanks, Jan
