Store an array, and get back an object?

    On one page I store an array (from a form submission) which looks like this:

    Array
(
    [id] => 8
    [form_id] => 1
    [date_created] => 2013-06-15 20:47:48
    [is_starred] => 0
    [is_read] => 0
)

    On the next page I fetch the array out of the session and it now looks like this:

    Recursive_ArrayAccess Object
(
    [container:protected] => Array
        (
            [id] => 10
            [form_id] => 1
            [date_created] => 2013-06-15 21:26:42
            [is_starred] => 0
            [is_read] => 0
        )
)

    I can still access this object like an array, but just wondering what the reason for this apparent change is.

    Actually, I can access elements of the array, but I cannot iterate over it. I need to be able to get the same data out of the session as I put in. Do I need to serialize data before it goes in?

    I’ve tried using json_encode() and json_decode() to translate my data between arrays and strings, and that cleanly gives me the correct data back when retrieving from the session. The documentation does suggest that I should not have to do that, however.

    Internally, the session uses nested arrays to store data. So your array lives inside an internal, hidden array. The Recursive_ArrayAccess object is merely an object that implements the same interfaces that Arrays implement, but which gives us the ability to have arbitrarily nested associative and non-associative arrays in the collection.

    Rather than implement all of the other Array interfaces for Recursive_ArrayAccess (i.e. Iterable, which is implemented for WP_Session itself), I extended a toArray() method on the Recursive_ArrayAccess object.

    So instead of:

    $data = $wp_session['data'];

    You’d use:

    $data = $wp_session['data']->toArray();

    This method returns an Array, and you can iterate over it however you want.

    Thanks, I’ll give that a go.

    Thanks Eric. Works as expected.
