Note Submitter: phpguy at lifetoward dot com ---- I recommend that you take special note of the fact that an INTEGER value must be returned from a sorting callback function. So, let's say you want to sort arrays by a quotient of two of their elements and to do so you write something like: <?php function sorter($a, $b) { return $a['num']/$a['denom'] - $b['num']/$b['denom']; } ?> You may not get the result you want because probably $x['num']/$x['denom'] has absolute value less than 1 and you'll get a lot of "same value" effective results from the comparator function as integer rounding occurs. To solve this just boost up the quotients to be big integers, then subtract them: <?php function sorter($a, $b) { return 1000*$a['num']/$a['denom'] - 1000*$b['num']/$b['denom']; } ?>
