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

In PHP, slicing objects with strong typing can be achieved by utilizing methods to extract specific properties or subsets of the object. Here's an example demonstrating how to do this:


        <?php
        class Person {
            public string $name;
            public int $age;

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

        class People {
            private array $people;

            public function __construct() {
                $this->people = [];
            }

            public function addPerson(Person $person): void {
                $this->people[] = $person;
            }

            public function slicePeople(int $start, int $length): array {
                return array_slice($this->people, $start, $length);
            }
        }

        // Usage example
        $group = new People();
        $group->addPerson(new Person("Alice", 30));
        $group->addPerson(new Person("Bob", 25));
        $group->addPerson(new Person("Charlie", 35));

        $slicedPeople = $group->slicePeople(1, 2); // Gets Bob and Charlie
        print_r($slicedPeople);
        ?>
