one srand should do it :)

here's another little function

<?

function generateRandomNumbers($count,$min,$max, &$arr)
{
//check if count is bigger than the range of numbers between $min and $max
//this would lead to an endless loop...
if( $count > ($max - $min +1) )
{
return false;
}

do
{
$i = rand($min,$max);
}while( !in_array($i,$arr) );

$array[] = $i;

if( (--$count) > 0 )
{
return generateRandomNumbers($count,$min,$max,$arr)
}

return true;
}


srand ((double)microtime()*1000000);

generateRandomNumbers(5,0,10, $numbers = array() );

echo "<pre>";
print_r($numbers);
echo "</pre>";
?>
