如何在PHP中将对象数组定义为参数？

class Person {
    private $name;
    private $age;

    public function getName() {
        return $this->name;
    }

    public function setName($name) {
        $this->name = $name;
    }

    public function getAge() {
        return $this->age;
    }

    public function setAge($age) {
        $this->age = $age;
    }
}

function printPerson(array $persons) {
    foreach ($persons as $person) {
        echo "Name: " . $person->getName() . ", Age: " . $person->getAge() . "<br>";
    }
}

$person1 = new Person();
$person1->setName("John");
$person1->setAge(25);

$person2 = new Person();
$person2->setName("Jane");
$person2->setAge(30);

$persons = [$person1, $person2];

printPerson($persons);
