What is encapsulation with simple example in php?

encapsulation, php

Solution

Encapsulation is just wrapping some data in an object. The term "encapsulation" is often used interchangeably with "information hiding". Wikipedia has a pretty thorough article.

Here's an example from the first link in a Google search for 'php encapsulation':

<?php

class App {
     private static $_user;

     public function User( ) {
          if( $this->_user == null ) {
               $this->_user = new User();
          }
          return $this->_user;
     }

}

class User {
     private $_name;

     public function __construct() {
          $this->_name = "Joseph Crawford Jr.";
     }

     public function GetName() {
          return $this->_name;
     }
}

$app = new App();

echo $app->User()->GetName();

?>
