How does PHP handle user-defined data types compared to languages like C++?

PHP handles user-defined data types differently compared to languages like C++. In PHP, user-defined data types can be created using classes, which allow for encapsulation of data and methods. This provides a more object-oriented approach to handling data types compared to the more traditional struct-based approach in C++. 

<?php

// Define a class to create a user-defined data type
class Person {
    public $name;
    public $age;

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

    public function greet() {
        echo "Hello, my name is " . $this->name . " and I am " . $this->age . " years old.";
    }
}

// Create an instance of the Person class
$person1 = new Person("John", 30);

// Access properties and methods of the user-defined data type
echo $person1->name; // Output: John
$person1->greet(); // Output: Hello, my name is John and I am 30 years old.

?>
