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();
