Oh, and the code, by the way:
<?php
// .... your code to this point....
/* what is the difference between the ending balance and the charges? */
$totChargeDiff = ($totalCharges > $endingBal) ?
($endingBal + $totalCharges) : ($endingBal - $totalCharges);
echo number_format($totChargeDiff, 2, '.', '')."\t";
// .... and continue with your code here....
