class Person {
    public $name;
    public $age;
}

$person1 = new Person();
$person1->name = "John";
$person1->age = 25;

$person2 = new Person();
$person2->name = "Jane";
$person2->age = 30;

$person3 = new Person();
$person3->name = "Bob";
$person3->age = 35;

$people = array($person1, $person2, $person3);

// 删除$person2对象
unset($people[1]);

// 打印剩余的对象数组
print_r($people);
