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";
