Note Submitter: grzeniufication at gmail dot com ---- Just wanted to show off the beauty of PHPs spaceship operator in this use case. <?php // tested on PHP 7.1 $a = [2, 1, 3, 6, 5, 4, 7]; $asc = $desc = $a; usort($asc, function (int $a, int $b) { return ($a <=> $b); }); usort($desc, function (int $a, int $b) { return -($a <=> $b); }); print_r([ $a, $asc, $desc ]); /** * Getting ahead of myself but... If arrow function syntax was possible: * usort($asc, (int $a, int $b) => ($a <=> $b)); * usort($desc, (int $a, int $b) => -($a <=> $b)); */ ?>
