In PHP, how do I map objects with examples?

In PHP, mapping objects is a technique used to transform elements from one structure into another. This can be particularly useful when working with arrays of objects and you want to create a new array with modified or filtered values.

Example of Mapping Objects in PHP


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

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

    $users = [
        new User('Alice', 25),
        new User('Bob', 30),
        new User('Charlie', 35)
    ];

    $userNames = array_map(function($user) {
        return $user->name;
    }, $users);

    print_r($userNames);
    ?>
