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);

You could use array_rand() to take stuff out of the array at random and then
stuff it all back into another array.

Could someone show me a quick and simple way to randomly sort array
elements? I can't seem to pinpoint the correct parameters in the docs.
Thanks!
