本篇文章为大家展示了如何在PHP中实现一个装饰器模式,内容简明扼要并且容易理解,绝对能使你眼前一亮,通过这篇文章的详细介绍希望你能有所收获。
具体如下:
<?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();
