return 'x' number of random numbers

[scrupul0us]

im trying to return a variable # of random numbers between a fixed range without replacement

eg...
return: 3
range: (0-9)

valid output: 2,6,7
invalid output: 2,6,6

i know rand(0,$limit) will give me the range, but as for returning 3 numbers without replacement... thats beyond me!

$numbers = range(0,9);
shuffle($numbers);
list($rand1, $rand2, $rand3) = array_slice($numbers, 0, 3);

One trick could be to use [man]array_rand/man with [man]range/man:

$range = range(0, 9);
$rand_keys = array_rand($range, 3);
$rand_array = array();
foreach ($rand_keys as $rand_key) {
    $rand_array[] = $range[$rand_key];
}
echo implode(',', $rand_array);
