如何将数据库中的数据添加到php中的对象中，以便在加载时临时使用

<?php
// 连接数据库
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "database";

$conn = new mysqli($servername, $username, $password, $dbname);
if ($conn->connect_error) {
    die("连接失败: " . $conn->connect_error);
}

// 执行查询
$sql = "SELECT id, name, email FROM users";
$result = $conn->query($sql);

// 创建对象
class User {
    public $id;
    public $name;
    public $email;
}

// 将数据添加到对象中
$users = array();
if ($result->num_rows > 0) {
    while ($row = $result->fetch_assoc()) {
        $user = new User();
        $user->id = $row["id"];
        $user->name = $row["name"];
        $user->email = $row["email"];
        $users[] = $user;
    }
}

// 使用对象
foreach ($users as $user) {
    echo "ID: " . $user->id . "<br>";
    echo "Name: " . $user->name . "<br>";
    echo "Email: " . $user->email . "<br>";
    echo "<br>";
}

// 关闭数据库连接
$conn->close();
?>
