以下是网学网为您推荐的PHP-php设计模式 Builder(建造者模式)，希望本篇文章对您学习有所帮助。

复制代码 代码如下:
<?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();
