PHP: Count stdClass objects within array

Question

I have an array with stdClass objects as below. How would I count how many I have under Interviewee_Name?

Tried counting as I would do an array but get an error that I can't becaused of the stdClass Object and then unsure how to proceed from there

Array
(
    [0] => stdClass Object
        (
            [Interviewee_Name] => Array
                (
                    [0] => stdClass Object
                        (
                            [id] => rn_Interviewee_Name_DIR_27
                            [value] => Janusz Jasinski
                        )

                )

        )

Can you show what you tried to do? You should be able to count any array, regardless of what it contains. — Don't Panic

This'll get the number of elements under Interviewee_Name, but it'll count all elements, not just objects.

count($arr[0]->Interviewee_Name)

However, if you really only want to get the objects in Interviewee_Name, you'll need to array_filter the array to get only the objects, and then count that new array:

count(array_filter($arr[0]->Interviewee_Name, function ($el) {
    return (gettype($el) == 'object');
}));

The syntax for getting an element from an array looks like $arr['index'], but in this case Interviewee_Name is a property of an object so you need to use the object syntax: $obj->prop

So if I wanted to get the value, would I do $arr[0]->Interviewee_Name[0]->value?

@pee2pee What doesn't work, the second block of code to filter non-objects, or your code to get the value?

Ignore me - using $arr but I changed it to $a :-)

$array = json_decode(json_encode($formData), True);

I added that to before looking to do a count and it worked!

Yes, the second parameter indicates that json_decode will convert $formData into an associative array instead of an object, however, this is unnecessary overhead that could be avoided if you simply change how you get Interviewee_Name
