// Storing a value in the Registry $registry = new \Registry(); $registry->set('username', 'JohnDoe'); // Retrieving the stored value $username = $registry->get('username'); echo $username; // Output: JohnDoe
// Storing an array in the Registry $registry = new \Registry(); $registry->set('products', ['apple', 'banana', 'orange']); // Retrieving an element from the stored array $products = $registry->get('products'); echo $products[1]; // Output: bananaIn this example, we create a new Registry object and store an array of products with the key 'products'. We then use the "get" method to retrieve the array by its key and store it in the $products variable. We can access individual elements of the array by indexing it with square brackets, as shown in the echo statement. As for the package library, it is not specified in the given information. However, the naming convention of the "\Registry()" class suggests that it may be a part of a custom library created by the developer.
