将session变量与对象一起使用

Question

我创建了一个对象并赋值如下:

$ car_object =&new Car();

$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;
