In what situations would it be advisable to use a custom MySQL class instead of relying on pre-existing classes like the one from phpbb?

There may be situations where the pre-existing MySQL classes do not meet specific project requirements or performance needs. In these cases, creating a custom MySQL class allows for greater flexibility and control over database interactions. 

class CustomMySQL {
    private $connection;

    public function __construct($host, $username, $password, $database) {
        $this->connection = new mysqli($host, $username, $password, $database);
        if ($this->connection->connect_error) {
            die("Connection failed: " . $this->connection->connect_error);
        }
    }

    public function query($sql) {
        return $this->connection->query($sql);
    }

    public function fetchArray($result) {
        return $result->fetch_assoc();
    }

    public function escapeString($string) {
        return $this->connection->real_escape_string($string);
    }

    public function close() {
        $this->connection->close();
    }
}

// Example usage
$customMySQL = new CustomMySQL('localhost', 'username', 'password', 'database');
$result = $customMySQL->query("SELECT * FROM table");
while ($row = $customMySQL->fetchArray($result)) {
    // Process row data
}
$customMySQL->close();
