I needed to generate a random array of different(!) numbers, i.e. no number in the array should be duplicated. I used the nice functions from phpdeveloper AT o2 DOT pl but it didn't work as I thought. 

So I varied it a little bit and here you are:

function RandomArray($min,$max,$num) {

$ret = array();

// as long as the array contains $num numbers loop
while (count($ret) <$num) {
	do {
		$a = rand($min,$max);
		//
		#echo $a."<br />";
	}
	// check if $a is already in the array $ret 
	// if so, make another random number
	while (in_array($a,$ret));
	// add the new random number to the end of the array
	$ret[] = $a;
}
return($ret);

}

// generate an array of 3 numbers between 10 and 19
$ret = randomArray(10,19,3)

echo $ret[0]."-".$ret[1]."-".$ret[2];
