In PHP, how do I map objects for beginners?

Mapping objects in PHP can be a useful way to transform one set of objects into another, often changing their structure or content in the process. This is typically done using PHP's array functions, particularly `array_map()`, along with an anonymous function.

Here's a simple example of mapping objects in PHP:


        <?php
        class User {
            public $name;
            public $email;
            
            public function __construct($name, $email) {
                $this->name = $name;
                $this->email = $email;
            }
        }
        
        class UserDTO {
            public $fullName;
            public $emailAddress;
            
            public function __construct($fullName, $emailAddress) {
                $this->fullName = $fullName;
                $this->emailAddress = $emailAddress;
            }
        }
        
        // Array of User objects
        $users = [
            new User('John Doe', 'john@example.com'),
            new User('Jane Smith', 'jane@example.com')
        ];
        
        // Mapping User to UserDTO
        $userDTOs = array_map(function($user) {
            return new UserDTO($user->name, $user->email);
        }, $users);
        
        // Outputting results
        foreach ($userDTOs as $userDTO) {
            echo "Name: " . $userDTO->fullName . ", Email: " . $userDTO->emailAddress . "<br>";
        }
        ?>
