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)); */ ?> ---- Server IP: 72.52.91.14 Probable Submitter: 83.8.133.82 ---- Manual Page -- http://php.net/manual/en/function.usort.php Edit -- https://master.php.net/note/edit/120344 Del: integrated -- https://master.php.net/note/delete/120344/integrated Del: useless -- https://master.php.net/note/delete/120344/useless Del: bad code -- https://master.php.net/note/delete/120344/bad+code Del: spam -- https://master.php.net/note/delete/120344/spam Del: non-english -- https://master.php.net/note/delete/120344/non-english Del: in docs -- https://master.php.net/note/delete/120344/in+docs Del: other reasons-- https://master.php.net/note/delete/120344 Reject -- https://master.php.net/note/reject/120344 Search -- https://master.php.net/manage/user-notes.php
