Question

我创建了一个对象，并按如下方式赋值：

$ car_object =＆amp;新车（）;

$car_object->offer = 'Sale'; 
$car_object->type = 'Sport Car'; 
$car_object->location = "Buffalo, New york";

如何将$ car_object存储在会话变量中？如何从会话变量中获取$ car_object？

Answer 1

设置为会话：

$car_object = new Car();

$car_object->offer = 'Sale'; 
$car_object->type = 'Sport Car'; 
$car_object->location = "Buffalo, New york";

$_SESSION['car'] = $car_object;

从会话中获取：

$car_object = $_SESSION['car'];
echo $car_object->offer;

Answer 2

更简单的方法是：

class SessionObject
{
    public function __construct($key)
    {
        if(isset($_SESSION[$key]))
        {
            $_SESSION[$key] = array();
        }
        $this->____data &= $_SESSION[$key];
    }

    public function __get($key)
    {
        return isset($this->___data[$key]) ? $this->___data[$key] : null;
    }

    public function __set($key,$value)
    {
        $this->___data[$key] = $value;
    }
}

然后你可以使用这样的东西;

class CarSession extends SessionObject
{
    public function __construct()
    {
        parent::__construct('car'); //name this object
    }
    /*
        * Custom methods for the car object
    */
}

$Car = new CarSession();

if(!$car->type)
{
     $Car->type = 'transit';
}

这有助于在会话中存储对象的更易管理的框架。

例如：

class Currentuser extend SessionObject{}
class LastUpload  extend SessionObject{}
class UserData    extend SessionObject{}
class PagesViewed extend SessionObject{}

Answer 3

序列化对象并将其存储到会话中。以下是对此的完整讨论：PHP: Storing 'objects' inside the $_SESSION
