Push a single Object onto an array of Objects

Question

I have the object below:

    $user= 
    object(stdClass)(2) 
    { 
        ["questions"]=> object(stdClass)(1) { [0] => object(stdClass) } 
        ["num_root_responses_for_section"]=> string(1) "0" 
    }

I want add an object so that I will have an array of objects into the questions property.

$user->questions[] = $new_question_object;

Doesn't work as it isn't an array.

I want something like so:

object(stdClass)(2) 
    { 
        ["questions"]=> object(stdClass)(2) { 
            [0]=> object(stdClass), 
            [1]=> object(stdClass) }
        ["num_root_responses_for_section"]=> string(1) "0" 
    }

I understand that I can count it, increment the count, then add my object. Just looking for a better way.

If `questions` is an object, then it is not an array. You would have to write some logic to determine the max property number/name that exists and then add 1. You would be better using an array. — AbraCadaver, Jul 20 '15 at 19:15

It's not an array! It is an object with numerical property names. — AbraCadaver, Jul 20 '15 at 19:24
Why not do all you need to do with it as an array first then convert your final array to an object? — Kaspersky, Jul 20 '15 at 19:26
So I already have an object. I have to convert that object into an array in order to push an object I have (which must also be converted into an array) into it. Then I can take that array and cast it back to an object in order to get my object back. Sounds a little silly but I guess if it works. — allencoded, Jul 20 '15 at 19:30
Since you insist on using objects you can do this.. $users->questions->{'9'} = 'value'; where 9 in this case is your preferred index — Kaspersky, Jul 20 '15 at 19:51

You would be better using an array, and this is hackish but I was bored:

$n = max(array_keys(get_object_vars($user->questions)));
$user->questions->{$n+1} = $new_question_object;

Or shorter (not really):

$user->questions->{max(array_keys(get_object_vars($user->questions)))+1} = $new_question_object;

$users->questions->{'9'} = 'value';

where 9 in this case is your preferred index for that item.

yeah meaning I would have to count the objects and add 1 – allencoded Jul 20 '15 at 20:30
Yes. That's what you would have to do – Kaspersky Jul 20 '15 at 20:31
