Creating the structure for our project

Now, we are going to create the structure for our project. In the first chapter, we created the /var/www/learning-phalcon.localhost folder. If you have another location, go there and create the following directory structure:

Next, let's create the index.php file that will handle our application. This file will be the default file in our web server:

<?php

header('Content-Type: text/html; charset=utf-8');
mb_internal_encoding("UTF-8");

require_once __DIR__.'/../modules/Bootstrap.php';

$app = new Bootstrap('frontend');
$app->init();
?>

In the first two lines, we set the header and internal encoding to UTF-8. This is a good practice if you are going to use special characters / diacritics. In the fourth line, we include a file named Bootstrap.php. This file is the Bootstrap of our project, and we will create its content in a few moments. On the next lines, we create a new instance of Bootstrap with a default module (frontend), and we initialize it.

We will need to find a way to autoload any file in our application without manually including it. We will make use of the \Phalcon\Loader component that will register all our modules in the namespace. In the config folder, we will create a new file called loader.php with the following content:

<?php

$loader = new \Phalcon\Loader();

$loader->registerNamespaces(array(
    'App\Core'       => __DIR__ . '/../modules/Core/',
    'App\Frontend'   => __DIR__ . '/../modules/Frontend/',
    'App\Api'        => __DIR__ . '/../modules/Api/',
    'App\Backoffice' => __DIR__ . '/../modules/Backoffice/',
));

$loader->register();
?>
