note 91645 added to function.array-multisort

Update to array_msort(): instead of eval() using call_user_func_array(). If we get column sorting via $_GET it would be a serious security hole. Now it also accepts multiple options for each column: <?php $arr2 = array_msort($arr1, array('name'=>array(SORT_DESC,SORT_REGULAR), 'cat'=>SORT_ASC)); ?> Btw. this function is automatically case-insensitive, as you can see use of strtolower(). <?php function array_msort($array, $cols) { $colarr = array(); foreach ($cols as $col => $order) { $colarr[$col] = array(); foreach ($array as $k => $row) { $colarr[$col]['_'.$k] = strtolower($row[$col]); } } $params = array(); foreach ($cols as $col => $order) { $params[] =& $colarr[$col]; $params = array_merge($params, (array)$order); } call_user_func_array('array_multisort', $params); $ret = array(); $keys = array(); $first = true; foreach ($colarr as $col => $arr) { foreach ($arr as $k => $v) { if ($first) { $keys[$k] = substr($k,1); } $k = $keys[$k]; if (!isset($ret[$k])) $ret[$k] = $array[$k]; $ret[$k][$col] = $array[$k][$col]; } $first = false; } return $ret; } ?> ---- Server IP: 92.48.74.199 Probable Submitter: 83.31.234.112 ---- Manual Page -- http://www.php.net/manual/en/function.array-multisort.php Edit -- https://master.php.net/note/edit/91645 Del: integrated -- https://master.php.net/note/delete/91645/integrated Del: useless -- https://master.php.net/note/delete/91645/useless Del: bad code -- https://master.php.net/note/delete/91645/bad+code Del: spam -- https://master.php.net/note/delete/91645/spam Del: non-english -- https://master.php.net/note/delete/91645/non-english Del: in docs -- https://master.php.net/note/delete/91645/in+docs Del: other reasons-- https://master.php.net/note/delete/91645 Reject -- https://master.php.net/note/reject/91645 Search -- https://master.php.net/manage/user-notes.php
