// Use Composer Autoloader require 'vendor/autoload.php'; // Instantiate Class $example_class = new Example_Class();
// Set up Autoloader spl_autoload_register(function ($class) { include 'classes/' . $class . '.php'; }); // Instantiate Class $example_class = new Example_Class();In this example, we create a custom autoloader. We use the spl_autoload_register function to help register the autoload function in the system based on the traits of each class and look for the target file to load properly. This approach is ideal for phasing out a custom autoloader for readability. Package Library: A Package Library is a central storehouse of packages that contain classes of various types, such as PHP. It is also a way to manage dependencies. In these examples, we used a package library, Composer, to manage our packages and autoload our classes. Composer is one of the more popular package libraries used for PHP.
