[PHP] Builder Design Pattern Example

PatternBuilder_Product.php

<?php

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;
	}
}

class ProductBuilder{
	protected $product = NULL;
	protected $_configs = array();
	
	public function __construct($configs){
		$this->product = new Product();
		$this->_configs = $configs;
	}
	
	public function build(){
		$this->product->setSize($this->_configs['size']);
		$this->product->setType($this->_configs['type']);
		$this->product->setColor($this->_configs['color']);
	}
	
	public function getProduct(){
		return $this->product;
	}
}

// Array of configuration
$productConfigs = array('type' => 'shirt', 'size' => 'XL', 'color' => 'red');

// OLD WAY - our product configuration received from other functionality
// $product = new product();
// $product-> setType($productConfigs['type']);
// $product-> setSize($productConfigs['size']);
// $product-> setColor($productConfigs['color']);

// NEW WAY
$builder = new productBuilder($productConfigs);
$builder->build();
$product = $builder->getProduct();

echo "<pre>";
	print_r($product);
	// var_dump($product);
	// print_r($builder);
	// var_dump($builder);
echo "</pre>";
