Zend框架2 - 包含多维数组会话 [英] Zend Framework 2 - Sessions containing multidimensional arrays

问题描述

假设我有以下一组数据：

Suppose i have the following set of data:

$foobar = array(
    "foo" => array (
       "foo1" => 1,
       "foo2" => 2,
       "foo3" => 3
    ),
    "bar" => array (
        "bar1" => 1,
        "bar2" => 2,
        "bar3" => 3,
    ),
);

在标准的PHP，我可以做到以下几点：

In standard PHP, i could do the following:

$_SESSION['foobar'] = $foobar;

然后，打电话值，通过实例BAR2：

Then, to call values, by example bar2:

$_SESSION['foobar']['bar']['bar2'];

但是，我们在Zend框架2这样做呢？

But what about doing this in Zend Framework 2?

我已经设置引导与会话管理器的所有参数，集装箱已设置它。会议得到建立。所以，如果我这样做，举例：

I have already set bootstrap with all parameters for session manager, and container has been set with it. Sessions get created. So, if i do, by example:

$session = new Container('foobar');

和在那里放一个值：

$session->foo1 = 1;

这工作。同样的，如果我决定把数组作为会话变量：

this works. Same if i decide to put an array as session variable:

//placing the $foobar array defined before
$session->foobar = $foobar;

但我不知道我怎么能叫值。假如我想foo​​2的，我会做

But i don't know how can i call values. Supposing i want foo2, i'd do

echo $session->foobar->foo->foo2;

期待它会输出'2'，但我得到而不是错误：

于是，我就做

echo $session->foobar['foo']['foo2'];

但返回另一个错误。

but this returns another error.

所以，现在我不知道我应该怎么做来收集这些数据，或者我怎么可以存储会话变量不同。我需要这个做一个购物车，那么foo和bar是不同的产品。我怎么能这样做呢？

So now i don't know what should i do to gather those data, or how could i store session variables differently. I need this to make a shopping cart, so foo and bar are different products. How could i do this?

推荐答案

解决。首先，我创建父抵消这种方式：

Solved. First of all i created the parent offset this way:

$session->offsetSet("foobar", new ArrayObject());

（需要使用Zend的\\ STDLIB \\ ArrayObject的; 在你的脚本的顶部）。

现在我可以从那里创造什么：

Now i can create anything from there:

$session->foobar->foo = "foo1";
$session->foobar->bar = "bar1";

等回事。
为了得到他们，这是那么容易，因为它应该：

and so going on. To get them, it's as easy as it should:

echo $session->foobar->foo; //returns foo1

我希望这会帮助别人。

I hope this will help someone.
