PHP negatives keep adding
I have this code here....
$remaining = 0;
foreach($array as $value=>$row){
$remaining = $remaining + $row['remainingbalance'];
}
What its doing is that it is going through all the remaining balances in the array which are -51.75 and -17.85 with the code above I get -69.60 which is correct. But I am wondering how when its two negatives if they could subtract? Is that possible?
I tried this
$remaining = 0;
foreach($clientArrayInvoice as $value=>$row){
$remaining = $remaining + abs($row['remainingbalance']);
}
but it gives me 69.60 without the negative.
Anyone got any ideas?
my goal is to take -51.75 and -17.85 and come up with -33.90 only when its a negative to do subtract. otherwise add
