In PHP, how do I deduplicate objects with strong typing?

id, $seenKeys)) {
            $seenKeys[] = $object->id;
            $uniqueObjects[] = $object;
        }
    }

    return $uniqueObjects;
}

// Example usage
class SomeObject {
    public int $id;
    public string $name;

    public function __construct(int $id, string $name) {
        $this->id = $id;
        $this->name = $name;
    }
}

$objects = [
    new SomeObject(1, "Object 1"),
    new SomeObject(2, "Object 2"),
    new SomeObject(1, "Duplicate Object 1"),
];

$deduplicated = deduplicateObjects($objects);
print_r($deduplicated);
?>
