How can one effectively manage dependencies between included files and functions in a PHP project?

Managing dependencies between included files and functions in a PHP project can be effectively done by using autoloading mechanisms such as Composer's PSR-4 autoloading. This allows you to define namespaces and map them to directories, ensuring that the necessary files are loaded when a class or function is called. By following this approach, you can easily organize your project structure and avoid manual inclusion of files. 

// Composer's autoloader setup
require 'vendor/autoload.php';

// Define namespace and directory mapping
$loader = new \Composer\Autoload\ClassLoader();
$loader->addPsr4('App\\', __DIR__ . '/src');
$loader->register();

// Example usage
use App\MyClass;

$myObject = new MyClass();
$myObject->myMethod();
