PHP将DB值插入到类的值中

// 建立数据库连接
$servername = "数据库服务器地址";
$username = "数据库用户名";
$password = "数据库密码";
$dbname = "数据库名";

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

// 检查连接是否成功
if ($conn->connect_error) {
    die("连接失败: " . $conn->connect_error);
}

// 执行查询语句获取DB值
$sql = "SELECT column_name FROM table_name WHERE condition";
$result = $conn->query($sql);

// 将DB值插入到类的属性中
if ($result->num_rows > 0) {
    while ($row = $result->fetch_assoc()) {
        $value = $row["column_name"];
        
        // 将$value赋值给类的属性
        $class->property = $value;
    }
} else {
    echo "没有结果";
}

// 关闭数据库连接
$conn->close();
