Thanks rnewsham. It worked like a champ Modified code

sub create_database {
    print "Please enter the hostname:";
    chomp($hostname = <STDIN>);
    print "Please enter the name of the new MySQL database:";
    chomp($database = <STDIN>);
    $dsn = "dbi:$driver::$hostname:$port";
    
    print "Please type the MySQL root username:";
    chomp($username = <STDIN>);
    print "Please type the MySQL root password:";
    chomp($password = <STDIN>);

    $dbh = DBI->connect($dsn, $username, $password);
    $result = $dbh->do("create database `$database`");
    $dbh->do("use `$database`");

    if($result) {
        say "Database '$database' created successfully";
    } else {
        say "Database '$database' creation failed";
        exit;
    }    
}
