A deck of cards

Deck.php
  1. namespace Deck;
  2.  
  3. require_once 'So-o.php';
  4.  
  5. require_once 'Card.php';
  6. require_once 'Hand.php';

Places the code of the class in its own namespace. Loads So-o and the Card class.

  1. defclass('Deck', null, 1, null, array('cards', 'top', 'shuffleWhenEmpty'), null, array('init', 'deal', 'hand', 'shuffle', 'check', 'toString'));

The Deck class inherits from the Object class. An instance has 3 properties: cards, the set of cards, top which holds the index in cards of the card on the top of the deck, i.e. the next which will be drawn, and shuffleWhenEmpty which if true automatically shuffles the deck when all the cards have been drawn. An instance redefines the messages init and toString. It implements the messages deal, hand, shuffle and check.
