<?php//装饰器模式-在不改变原有类的结构上，对类的功能那个作补充//武器基类abstract class Weapon{ abstract public function descriptions(); abstract public function cost();}//剑类class Glave extends Weapon{ public function descriptions(){ return 'Glave'; } public function cost(){ return "100"; }}//匕首类class Knife extends Weapon{ public function descriptions(){ return __CLASS__; } public function cost(){ return "80"; }}//斧类class Axe extends Weapon{ public function descriptions(){ return __CLASS__; } public function cost(){ return "200"; }}//属性类class Property extends Weapon{ protected $_weapon = null; protected $_price = 0; protected $_descriptions = ''; public function __construct(Weapon $weapon){ $this->_weapon = $weapon; } public function cost(){ return $this->_weapon->cost() + $this->_price; } public function descriptions(){ return $this->_weapon->descriptions().$this->_descriptions; }}//力量属性class Strength extends Property{ protected $_price = 30; protected $_descriptions = '+ Strength';}//敏捷属性class Agility extends Property{ protected $_price = 50; protected $_descriptions = '+ Agility';}//智力属性class Intellect extends Property{ protected $_price = 20; protected $_descriptions = '+ Intellect';}$weapon = new Agility(new Strength(new Strength(new Glave())));echo $weapon->cost();echo $weapon->descriptions(); |
希望本文所述对大家PHP程序设计有所帮助。
