在php中访问多维json数组的正确方法是什么？

Question

I'm working on cookies that contain multidimensional JSON object array and I have bit of a problem accessing them. Kindly help me.

Here's a look at my problem: I access the values from the html element and encode it before storing it into a variable,

var cookie_items = JSON.stringify({id: value, quantity: 1});

then I push this object into an array,

cookie_array.push(cookie_items);

finally, I push the cookie_array into another array with the associative name 'all',

final_cookie_array['all'] = cookie_array;

When I log final_cookie_array in the browser console, the output looks like this:

Object {all: Array[2]}
  all: Array[2]
    0: "{"id":"6","quantity":1}"
    1: "{"id":"2","quantity":1}"

When I echo the cookie array in PHP, ie, $_COOKIE['cookie_name']; it outputs the following:

[object Object]

But when I try echoing $_COOKIE['cookie_name']['all']; nothing gets displayed.

Can somebody please help me deal with this? Thanks.

Try like example below

<?php
   $json = '{"a":1,"b":2,"c":3,"d":4,"e":5}';
   $arr = json_decode($json,true);
   var_dump($arr);
?>
