In PHP, how do I sort objects with SPL?

In PHP, the Standard PHP Library (SPL) provides a convenient way to sort objects. You can use the `SPLSort` class which offers functionalities to sort arrays or objects based on specified criteria. Below is an example that demonstrates how to sort an array of objects using SPL.


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

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

        // Sample array of Person objects
        $people = [
            new Person("Alice", 30),
            new Person("Bob", 25),
            new Person("Charlie", 35),
        ];

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

        // Output the sorted array
        foreach ($people as $person) {
            echo $person->name . " (" . $person->age . ")<br>";
        }
        ?>
