php设计模式 Builder (建造者模式)
php有23种设计模式,你全都知道吗?下面用代码介绍建造者模式(Builder模式)
<?php
/**
* 建造者模式
*
* 将一个复杂对象的构建与它的表示分离,使用同样的构建过程可以创建不同的表示
*/
class Product {
public $_type = null;
public $_size = null;
public $_color = null;
public function setType($type) {
echo "set product type<br/>";
$this->_type = $type;
}
public function setSize($size) {
echo "set product size<br/>";
$this->_size = $size;
}
public function setColor($color) {
echo "set product color<br/>";
$this->_color = $color;
}
}
$config = array(
"type" => "shirt",
"size" => "xl",
"color" => "red",
);
// 没有使用bulider以前的处理
$oProduct = new Product();
$oProduct->setType($config['type']);
$oProduct->setSize($config['size']);
$oProduct->setColor($config['color']);
// 创建一个builder类
class ProductBuilder {
var $_config = null;
var $_object = null;
public function ProductBuilder($config) {
$this->_object = new Product();
$this->_config = $config;
}
public function build() {
echo "--- in builder---<br/>";
$this->_object->setType($this->_config['type']);
$this->_object->setSize($this->_config['size']);
$this->_object->setColor($this->_config['color']);
}
public function getProduct() {
return $this->_object;
}
}
$objBuilder = new ProductBuilder($config);
$objBuilder->build();
$objProduct = $objBuilder->getProduct();其他相关设计模式:
