note 25033 added to function.shuffle

And for the last optimized sample: for($c = count($arr) - 1; $c > 0; $c--) { $r = mt_rand(0, $c); $v = $arr[$c]; $arr[$c] = $arr[$r]; $arr[$r] = $v; } You can stop when c == 0, instead of c < 0, as the element $arr[0] is the only remaining element that has not been selected in the previous random selections, so $r in that last loop would always be 0, and the element would only swap with itself. -- http://www.php.net/manual/en/function.shuffle.php http://master.php.net/manage/user-notes.php?action=edit+25033 http://master.php.net/manage/user-notes.php?action=delete+25033 http://master.php.net/manage/user-notes.php?action=reject+25033
