note 85957 added to function.sort

Please, think twice before creating (and posting) your homemade solution for ordering an array by a field. PHP already has a solution for this; usort, which is about x40 faster than any other solution. If creating a callback for each case hurts, you can do something like this: <?php /** * @author Lucas Dománico */ class util { static private $sortfield = null; static private $sortorder = 1; static private function sort_callback(&$a, &$b) { if($a[self::$sortfield] == $b[self::$sortfield]) return 0; return ($a[self::$sortfield] < $b[self::$sortfield])? -self::$sortorder : self::$sortorder; } static function sort(&$v, $field, $asc=true) { self::$sortfield = $field; self::$sortorder = $asc? 1 : -1; usort($v, array('util', 'sort_callback')); } } # Usage: for($i=0; $i<1000 ;$i++) { $v[] = array('score'=>rand(1,10000)); } util::sort($v, 'score'); ?> ---- Server IP: 201.216.232.3 Probable Submitter: 190.139.65.244 ---- Manual Page -- http://www.php.net/manual/en/function.sort.php Edit -- https://master.php.net/note/edit/85957 Del: integrated -- https://master.php.net/note/delete/85957/integrated Del: useless -- https://master.php.net/note/delete/85957/useless Del: bad code -- https://master.php.net/note/delete/85957/bad+code Del: spam -- https://master.php.net/note/delete/85957/spam Del: non-english -- https://master.php.net/note/delete/85957/non-english Del: in docs -- https://master.php.net/note/delete/85957/in+docs Del: other reasons-- https://master.php.net/note/delete/85957 Reject -- https://master.php.net/note/reject/85957 Search -- https://master.php.net/manage/user-notes.php
