How to set up multiple PDO database connections in slim 4 and access them in a repository? - pdo

Question

I tried to set up SLIM 4 with 2 PDO database connections.
I can't access the db nor db2 from a repository.
I guess I'm doing something wrong
I followed the slim 4 skeleton.
I created a db.php file in app for adding the db's definition in the container
I included db.php in index.php
I tried to access the db or db2 from a repository but it is not working
Here are my files :
app/db.php
declare(strict_types=1);
use PDO;
use DI\ContainerBuilder;
return function (ContainerBuilder $containerBuilder) {
// Global Settings Object
$containerBuilder->addDefinitions([
'db' => function (ContainerInterface $c) {
$settings = $c->get('settings');
$dbSettings = $settings['db'];
return new PDO('mysql:host=' . $dbSettings['host'] . ';dbname=' . $dbSettings['db'], $dbSettings['username'], $dbSettings['password'], $dbSettings['options']);
},
'db2' => function (ContainerInterface $c) {
$settings = $c->get('settings');
$dbSettings = $settings['db2'];
return new PDO('mysql:host=' . $dbSettings['host'] . ';dbname=' . $dbSettings['db'], $dbSettings['username'], $dbSettings['password'], $dbSettings['options']);
}
]);
};
public/index.php
declare(strict_types=1);
use App\Application\Handlers\HttpErrorHandler;
use App\Application\Handlers\ShutdownHandler;
use App\Application\ResponseEmitter\ResponseEmitter;
use DI\ContainerBuilder;
use Slim\Factory\AppFactory;
use Slim\Factory\ServerRequestCreatorFactory;
require __DIR__ . '/../vendor/autoload.php';
// Instantiate PHP-DI ContainerBuilder
$containerBuilder = new ContainerBuilder();
if (false) { // Should be set to true in production
$containerBuilder->enableCompilation(__DIR__ . '/../var/cache');
}
// Set up settings
$settings = require __DIR__ . '/../app/settings.php';
$settings($containerBuilder);
// Set up dependencies
$dependencies = require __DIR__ . '/../app/dependencies.php';
$dependencies($containerBuilder);
// Set up db, added by PF
$db = require __DIR__ . '/../app/db.php';
$db($containerBuilder);
// Set up repositories
$repositories = require __DIR__ . '/../app/repositories.php';
$repositories($containerBuilder);
// Build PHP-DI Container instance
$container = $containerBuilder->build();
// Instantiate the app
AppFactory::setContainer($container);
$app = AppFactory::create();
$callableResolver = $app->getCallableResolver();
// Register middleware
$middleware = require __DIR__ . '/../app/middleware.php';
$middleware($app);
// Register routes
$routes = require __DIR__ . '/../app/routes.php';
$routes($app);
/** #var bool $displayErrorDetails */
$displayErrorDetails = $container->get('settings')['displayErrorDetails'];
// Create Request object from globals
$serverRequestCreator = ServerRequestCreatorFactory::create();
$request = $serverRequestCreator->createServerRequestFromGlobals();
// Create Error Handler
$responseFactory = $app->getResponseFactory();
$errorHandler = new HttpErrorHandler($callableResolver, $responseFactory);
// Create Shutdown Handler
$shutdownHandler = new ShutdownHandler($request, $errorHandler, $displayErrorDetails);
register_shutdown_function($shutdownHandler);
// Add Routing Middleware
$app->addRoutingMiddleware();
// Add Error Middleware
$errorMiddleware = $app->addErrorMiddleware($displayErrorDetails, false, false);
$errorMiddleware->setDefaultErrorHandler($errorHandler);
// Run App & Emit Response
$response = $app->handle($request);
$responseEmitter = new ResponseEmitter();
$responseEmitter->emit($response);
src/Domain/ObContact/ObContactRepository.php

namespace App\Domain\ObContact;
use PDO;
class ObContactRepository

/**

private $db;
private $db2;
/**

Did you install PDO?
$ composer require faapz/pdo
