# Script 7.4 - factory.php
// This page uses the ShapeFactory class (Script 7.2).
// Load the class definitions:
require 'ShapeFactory.php';
require 'Shape.php';
require 'Triangle.php';
require 'Rectangle.php';
// Minimal validation:
if (isset($_GET['shape'], $_GET['dimensions'])) {
// Create the new object:
$obj = ShapeFactory::Create($_GET['shape'], $_GET['dimensions']);
// Print a little introduction:
echo "<h2>Creating a {$_GET['shape']}...</h2>";
// Print the area:
echo '<p>The area is ' . $obj->getArea() . '</p>';
// Print the perimeter:
echo '<p>The perimeter is ' . $obj->getPerimeter() . '</p>';
} else {
echo '<p class="error">Please provide a shape type and size.</p>';
}
// Delete the object:
unset($obj);
?>
</body>
</html>
This will give the result of area = 168 and perimeter = 52
---------------------------------------
Triangle Test:
factory.php?shape=triangle&dimensions[]=12&dimensions[]=14&dimensions[]=5
This will give the result of area = 29.230762904858 and perimeter = 31
---------------------------------------
Shapes not exist Test:
factory.php?shape=tfriangle&dimensions[]=12&dimensions[]=14&dimensions[]=5
