This way can be array reversed in situ: <?php function arrayReverse(&$arr){ if (!is_array($arr) || empty($arr)) { return; } $rev = array(); while ( false !== ( $val = end($arr) ) ){ $rev[ key($arr) ] = $val; unset( $arr[ key($arr) ] ); } $arr = $rev; } // usage example $test = array(5, 'c'=>100, 10, 15, 20); arrayReverse($test); var_export($test); // result: array ( 3 => 20, 2 => 15, 1 => 10, 'c' => 100, 0 => 5, ) ?> ---- Server IP: 69.147.83.197 Probable Submitter: 80.87.209.10 ---- Manual Page -- http://www.php.net/manual/en/function.array-reverse.php Edit -- https://master.php.net/note/edit/108988 Del: integrated -- https://master.php.net/note/delete/108988/integrated Del: useless -- https://master.php.net/note/delete/108988/useless Del: bad code -- https://master.php.net/note/delete/108988/bad+code Del: spam -- https://master.php.net/note/delete/108988/spam Del: non-english -- https://master.php.net/note/delete/108988/non-english Del: in docs -- https://master.php.net/note/delete/108988/in+docs Del: other reasons-- https://master.php.net/note/delete/108988 Reject -- https://master.php.net/note/reject/108988 Search -- https://master.php.net/manage/user-notes.php
