Question

I’m trying this mini framework for the first time and this is my first time at all using justa a framework:)
I added the doctrine service to my index.php file like this:

$app->register(new Silex\Provider\DoctrineServiceProvider(), array(
    'db.options' => array(
        'driver'   => 'pdo_sqlite',
        'path'     => __DIR__.'/../include/database.sqlite',
    ),
));

and I create a new file with a class with a static method that resturn an array, for example.

<?php

namespace MyNameSpace;


class myClass{

    static function getStuff(){


       return array(1 => array('foo'=> 'bar',
                               'bar' => 'foo',
                              )
                   );

    }

}

As you can see it’s hardcoded so I decide to use a database (sqlite is enought) but I don’t know how to get access to $app variable inside my file.

On the other way, all the tutorials that I can find online are confusing and referred to a old Silex’s version with the .phar file that now is deprecated, and the directory structures of all examples I found are differente from mine (taken from the fat Silex zip file)

The directory structure of my project is this:

├── composer.json
├── composer.lock
├── src
│   └── MyNameSpace
│       └── myClass.php
├── vendor
│   └── composer
│   └── doctrine
│   └── silex
│   └── ...
│   └── **autoload.php**
└── web
    └── css
    └── img
    └── js
    └── views
    └── .htaccess
    └── index.php

First thing you need to know is that accessing $app is a bad practice. You should DI when it is possible. If you really want to do that, check the code below.

Inside index.php (usually bootstrap.php) declare a new service:

$app['my_class'] = $app->share(function() use ($app) {
    // Retrieve the db instance and create an instance of myClass
    return new \MyNameSpace\myClass($app['db']);
});

Add a constructor sur myClass:

namespace MyNameSpace;

class myClass
{
    /**
     * The connection
     *
     * @var \Doctrine\DBAL\Connection
     */
    private $db;

    /**
     * Constructor
     *
     * @param $db \Doctrine\DBAL\Connection
     */
    public function __construct($db)
    {
        $this->db = $db;
    }

    // ...
}

Then you can retrieve a fully initialized instance of myClass like this:

$myClass = $app['my_class'];
