How to filter out an object from an array of objects?

I’ve got an array of objects as follows ; how can I filter out (remove) the objects that have admins->member = 11 ?

In this example, the resulting array object would only have the 1st object that [245] at the start.

Array
(
    [245] => stdClass Object
        (
            [name] => Programmation Web

I’d like to check against the index

$arr = array_filter($arr, function($item) {
    if (!isset($item->admins) || !is_array($item->admins)) {
        return false;
    }
    foreach ($item->admins as $admin) {
        if ($admin->member == 11) {
            return true;
        }
    }
    return false;
});
