note 124046 added to array.sorting

I tend to use the following code for adding a sort on the keys when different values have the same key: <?php $arr = array(); $res = $db->query("some sql"); while ($row = $res->fetchRow()) { $key = trim($row[0]); // I know... 'colname' is better $value = trim($row[1]); $arr[$key] = $value . "_" . sprintf('%09d', $key); // number } arsort($arr); foreach ($arr as $key=>$value_and_key) { list($value, $dummykey) = explode("_", $value_and_key); echo "$key and $value"; // reverse sorted by value, then key } ?> Appending the key to the value makes arsort a kind of dual sort. No need for extra user-defined functions...
