class Item { public $name; public $price; public function __construct($name, $price) { $this->name = $name; $this->price = $price; } } $item1 = new Item("Book", 10.99); $item2 = new Item("CD", 7.99); echo $item1->name; // Output: Book echo $item2->price; // Output: 7.99
namespace MyApp; class Item { public $name; public $price; public function __construct($name, $price) { $this->name = $name; $this->price = $price; } }Example 2 is similar to Example 1, but it introduces a namespace. A namespace is a way to group related classes together, and it helps prevent naming conflicts. The Item class is defined within the MyApp namespace, and any code that uses this class will need to reference this namespace. Based on the examples provided, it is difficult to determine a specific package library that is being used with the item __construct function. However, it is likely that the code is part of a larger project that may include other classes and libraries.
