Access data inside stdObject - php

Question

I have stdClass data after submitting the form:
"Array
(
[0] => stdClass Object
(
[username] => stdClass Object
(
[0] => 1001037
[1] => AARONJAMES
[2] => 1
[3] => ULTIMA (Red)
[4] => 1001037|1
[staff_id] => 1001037
[username] => AARONJAMES
[fkhouseid] => 1
[hname] => ULTIMA (Red)
[id] => 1001037|1
[$$hashKey] => object:13
)
[$$hashKey] => object:6
[points] => 50
)
[1] => stdClass Object
(
[username] => stdClass Object
(
[0] => 1001075
[1] => AARONKOH
[2] => 2
[3] => NACHOZZ (Purple)
[4] => 1001075|2
[staff_id] => 1001075
[username] => AARONKOH
[fkhouseid] => 2
[hname] => NACHOZZ (Purple)
[id] => 1001075|2
[$$hashKey] => object:14
)
[house] =>
[points] => 20
[$$hashKey] => object:306
)
)"
I want to access id variable inside username array to explode it later and insert data into database.
I tried to use to access it but it didnt work:
foreach ($persons as $key => $object) {
var_dump($persons[$key]->id);
}
How can I access id variable inside username?

Answer 1

Assuming $persons have array. You can try like below.
foreach ($persons as $key => $object) {
var_dump($object->username->id);
}

Answer 2

As per my comments you should try this
foreach ($persons as $key => $object) {
echo $object[$key]->username->id;
}
some details about array
$key is the index number of person array.
username is the stdClass Object so you can get like this ->username.
