What I'm building:

• Pricing calculator

• There are 4 products each having their own specific pricing rules that vary from user input

• The person can choose between 1 product or all products

  /*

  • Use Factory Pattern to build objects */

  class ProductFactory { public static function createProduct($type) { switch ($type) { case 'solution1': return new Solution1Product(); break;

           case 'solution2':
               return new Solution2Product();
               break;
  
           case 'solution3':
               return new Solution3Product();
               break;
  
           case 'solution4':
               return new Solution4Product();
               break;
       }
  
   }
  

  }

  /*

  • Abstract Product */

  abstract class AbstractProduct { protected $price; protected $max_limit; protected $max_amount;

   abstract public function calculatePrice($dob, $gender, $amount);
  

  }

  /*

  • Solution 1 Product */ class Solution1Product extends AbstractProduct { protected $max_limit = 50000;

    function __contruct() { print "Test"; return "Solution1"; }

    function calculatePrice($dob, $gender, $amount) { $this->price = $price; $price = 55; //@TODO go lookup price from tables, figure out dob, gender, stuff

     $rate = 1.03;
     $amount = $rate * $price;
     return $amount;
    

    } }

  $solution1 = ProductFactory::createProduct('solution1'); print $solution1->calculatePrice("02/25/1982", "male", "100000"); print $solution1::$price;

Updated: What I'm building:

• Pricing calculator

• The person can choose between 1 product or all products

Should I have a Calculator class to determine product pricing or leave the calculations in each product type?
