Accessing second array (non object) in decoded JSON - php

Question

I'm trying to access the second array (contacts) in this decoded json to grab the ID next to first_name (the two ID keys could be different), but the second array doesn't seem to be an object so I can't find a loop which can acces it:
stdClass Object (
[data] => Array (
[0] => stdClass Object (
[account_key] => jvg7qgtw2btrlmpigrq2zpco48eegxvv
[is_owner] => 1
[id] => 1
[name] => test test
[display_name] => test test
[balance] => 0
[paid_to_date] => 0
[updated_at] => 1578494555
[archived_at] =>
[address1] => Street
[address2] =>

)
)
)
[meta] => stdClass Object (
[pagination] => stdClass Object (
[total] => 1
[count] => 1
[per_page] => 15
[current_page] => 1
[total_pages] => 1
[links] => Array ( )
)
)
)
This is what I've tried, but it doesn't find anything:
$person = getclient($itemid);
$person_data = json_decode($person);
foreach ($person_data->contacts as $key => $item)
{
$itemid = $item->id . "<br />";
}

Answer 1

$person_data contains the data property, which is an array of objects.
foreach ($person_data->data as $person) {
foreach ($person->contacts as $contact) {
echo $contact->id . '<br>';
}
}
