In PHP, how do I reduce objects for beginners?

In PHP, reducing objects is a helpful technique for minimizing data by filtering or transforming the properties of an object. This can be particularly useful when you only need a subset of an object’s properties.

Here’s a simple example demonstrating how to reduce an object to retain specific properties:


        <?php
        class User {
            public $name;
            public $email;
            public $age;

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

        $user = new User("John Doe", "john@example.com", 30);

        // Function to reduce object
        function reduceObject($object, $fields) {
            return array_intersect_key((array)$object, array_flip($fields));
        }

        $reducedUser = reduceObject($user, ['name', 'email']);

        print_r($reducedUser);
        ?>
