Random data container using magic methods get and set

Question

Is it possible to create a PHP class that can hold whatever type of data you throw at it, even recursively, using magic methods?

I saw this: PHP - Indirect modification of overloaded property

but it doesn't handle recursive data:

class ActiveRecord extends Creator {

}

$a = new ActiveRecord();

$a->_id = "123456789";
$a->persona_info = [
    "name" => "Bob",
    "surnames" => ["First", "Second", "Third"]
];
$a->history = [
    "logins" => [
        [
            "date" => "1999",
            "ip" => "1.2.3.4"
        ],
        [
            "date" => "1129",
            "ip" => "1.2.3.4"
        ]
    ],
    "purchases" => [
        [
            "date" => "1819",
            "amount" => "1884"
        ],
        [
            "date" => "1459",
            "amount" => "14"
        ]
    ]
];

var_dump($a->history->logins);

That gives me:

PHP Notice:  Trying to get property of non-object in /tmp/x.php on line 90
PHP Stack trace:
PHP   1. {main}() /tmp/x.php:0
NULL

Trying to investigate further, I see that $a->history is a plain php array instead of a Value object (or even a Creator object.

Dont think most people tend to click through. I did not at first read, anyway you are using the modified version of the `creator` class? — DarkBee, Apr 06 '15 at 17:48
You need to return another object that also has magic methods, not the raw array. — Barmar, Apr 06 '15 at 17:53
@Barmar Where should that be? In the `__get` method of `Value`? — alexandernst, Apr 06 '15 at 17:56
At first glance i'm not sure you can convert the `login` key to a `StdClass`, because how would you retrieve the values in it? A property name can't start with a numeric value. You will need to alter the `__get` method and create a class that is able to retrieve these value for instance with the interface `ArrayAccess` — DarkBee, Apr 06 '15 at 18:07

The problem is $a->history is an array and not a object. It should be var_dump($a->history['logins']);

Yes, that would work for this specific case, but my question is more broad. I'm trying to access values using `->`, which means that each value should be an object, which then should contain all children values, etc. – alexandernst Apr 06 '15 at 17:49
That's the problem. If you want it to be a object then you need to declare it differently and not like that. – SameOldNick Apr 06 '15 at 17:50
OP is using magic methods to modify passed data, in this case convert array to `StdClass`, see linked answer – DarkBee Apr 06 '15 at 17:51
