PHP设计模式——建造者模式builder

建造者模式是将一个复杂对象的构建与它的表示分离，使得同样的构建过程可以创建不同的表示，它着重于一步步构造一个复杂对象。

class product{
	protected $_type = '';
	protected $_size = '';
	protected $_color = '';

	public function setType($type){
		$this->_type = $type;
	}

	public function setSize($size){
		$this->_size = $size;
	}

	public function setColor($color){
		$this->_color = $color;
	}

	public function getType(){
		return $this->_type;
	}

	public function getSize(){
		return $this->_size;
	}

	public function getColor(){
		return $this->_color;
	}
}

class productBuilder{
	protected $_product = NULL;
	protected $_configs = array();

	public function __construct($configs){
		$this->_product = new product();
		$this->_configs = $configs;
	}

	public function build(){
		$this->_product->setType($this->_configs['type']);
		$this->_product->setSize($this->_configs['size']);
		$this->_product->setColor($this->_configs['color']);
	}

	public function getProduct(){
		return $this->_product;
	}
}

$configs = array('type'=>'shirt', 'size'=>'XL', 'color'=>'red');
$builder = new productBuilder($configs);
$builder->build();
$product = $builder->getProduct();
echo $product->getColor();

以上就介绍了PHP设计模式——建造者模式builder，包括了对象方面的内容，希望对PHP教程有兴趣的朋友有所帮助。
