note 19037 added to function.array-multisort

If you want to sort a multidimentionnal array based on a certain row, the easiest way I found was using usort() and a comparison function of my own. The comparison function is called with two elements of the array. Then, in the function, as the two elements are also arrays (we are dealing with a multidimentionnal one), the comparison can be made on any row: if ($a[2] > $b[2]) return 1; ... See the definition of usort() for that. -- http://www.php.net/manual/en/function.array-multisort.php http://master.php.net/manage/user-notes.php?action=edit+19037 http://master.php.net/manage/user-notes.php?action=delete+19037 http://master.php.net/manage/user-notes.php?action=reject+19037
