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

In PHP, sorting objects with strong typing involves using the appropriate methods provided by PHP. One common approach is to implement the `Comparable` interface and use the `usort` function to sort an array of objects. Below is an example demonstrating this process.


        name = $name;
                $this->age = $age;
            }
        }

        $people = [
            new Person("Alice", 30),
            new Person("Bob", 25),
            new Person("Charlie", 35),
        ];

        usort($people, function($a, $b) {
            return $a->age <=> $b->age; // Sorting by age
        });

        foreach ($people as $person) {
            echo $person->name . ' is ' . $person->age . ' years old.
';
        }
        ?>
