Before you add a number to a string make sure that the number is not in
any of the other ones if they exist.
Use a do-while loop on it...
$one = rand( 1,20 );
do {
$two = rand( 1, 20 );
}while( $two == $one );
do {
$three = rand( 1, 20 );
}while( ($three == $one) && ($three == $two) );
echo "One: $one\n";
echo "Two: $two\n";
echo "Three: $three\n";
