The function you need I think is shuffle()

Thanks all for you submissions. This is what I came up with, where
$this_key is a random selection from the array $the_exploded_ids. I
don't know why, but, array_rand() won't work with selection quanity
parameter of less than 2. Anybody know why?
srand ((float) microtime() * 1000);
$input
This appears to work
// Normal array
$a1 = Array(1, 2, 3, 4, 5, 6, 7, 8, 9, 10);
srand((float) microtime() * 1000);
$a_temp = array_rand($a1, sizeof($a1));
// Random array
while (list(, $value) = each($a_temp)) {
$a2[] = $a1[$value];
}
print_r($a2);

But if array_rand() truly pulls out random keys, how do you guarantee
that you are not randomly pulling out the same key as you iterate
through the array?
Perhaps you could set the number of keys to return, to the size of the
array, and somehow, magically, all the keys would be included in the
You could use array_rand() to take stuff out of the array at random and then
stuff it all back into another array.
