Yes, shuffle doesn't shuffle well: I made some experiments and found that shuffling a 10 row array would leave the first element in place about three times more often than bringing the last element to the front! But I'd suppose that the following is somewhat faster (don't forget to srand, of course!): function my_shuffle(&$array) { for ($j=count($array)-1; $j>0; $j--) { if (($i = rand(0,$j))<$j) {$swp=$array[$i]; $array[$i]=$array[$j]; $array[$j]=$swp;} } } --was-- Yes, shuffle doesn't shuffle well: I made some experiments and found that shuffling a 10 row array would leave the first element in place about three times more often than bringing the last element to the front!
