Time for action — including the classes directory


In order for us to use our classes, we'll need to add some code to Bones so that we can automatically load class names as they are used. This will achieve that, so we don't have to continuously include more files as we add new classes.

Add the following code to lib/bones.php:

<?php
define('ROOT', __DIR__ . '/..');
require_once ROOT . '/lib/sag/src/Sag.php';
function __autoload($classname) {
include_once(ROOT . "/classes/" . strtolower($classname) . ".php");
}


What just happened?

We added a __autoload function to our Bones library that will give PHP a last attempt to load a class name if it can't find the class. The __autoload function is passed the $classname, and we use the $classname to find the file of the named class. We are making the requested $classname lowercase using the strtolower function so that we can find the named file. We then added the root of the working directory with the ROOT constant and the classes folder....
