Access all variable instances of specific classes

[andygrant]

Hi

 

I was wondering if anyone knew if it was possible to access all variable that are instances of a specific type of object. So if I had a user class and created a few of these through the code could I get access to all later without keeping track in some way as they are created.

 

Thanks in advance

you can use a static variable in the class to keep track:

 

class user {

  private static $users = array();

  function __construct ( ) {

    self::$users[] = $this;
  }

  static function getUsers ( ) {
    return self::$users;
  }
}

$user1 = new user();
$user2 = new user();
$user3 = new user();

$users = user::getUsers();

That should do the trick, thanks.
