$username = "your_username";
$password = "your_password";
$dbname = "your_database";

$conn = new mysqli($servername, $username, $password, $dbname);

if ($conn->connect_error) {
    die("连接失败：" . $conn->connect_error);
}

$sql = "SELECT * FROM users";
$result = $conn->query($sql);

if ($result->num_rows > 0) {
    while($row = $result->fetch_assoc()) {
        echo "ID: " . $row["id"]. " - Name: " . $row["name"]. "<br>";
    }
} else {
    echo "0 结果";
}

$conn->close();
?>

    public $color;

    public function __construct($brand, $color) {
        $this->brand = $brand;
        $this->color = $color;
    }

    public function drive() {
        echo "Driving the " . $this->brand . " car";
    }
}

$car = new Car("BMW", "blue");
$car->drive();
?>
