How to access PDO instance created with DI in dependencies.php - php

Question

How do I get the PDO connection in my model class that was created in dependicies.php?
I have Controller and Model classes.
My route:
$app->group('/users', function (Group $group) {
$group->get('', [UsersController::class, 'getAll'], function (Request $request, Response $response) {
return $response;
});
});
My Controller:
namespace App\Application\Controllers;
use Psr\Http\Message\ResponseInterface as Response;
use Psr\Http\Message\ServerRequestInterface as Request;
use App\Application\Models\UsersService;
class UsersController
{
private $_usersSvc;
public function __construct()
{
$this->_usersSvc = new UsersService();
}
public function getAll(Request $request, Response $response)
{
$uri = $request->getUri();
parse_str($uri->getQuery(), $params);
$result = $this->_usersSvc->getAll($params);
$response->getBody()->write(json_encode($result));
return $response;
}
My DI setup in dependencies.php
return function (ContainerBuilder $containerBuilder) {
$containerBuilder->addDefinitions([
LoggerInterface::class => function (ContainerInterface $c) {
$settings = $c->get(SettingsInterface::class);
$loggerSettings = $settings->get('logger');
$logger = new Logger($loggerSettings['name']);
$processor = new UidProcessor();
$logger->pushProcessor($processor);
$handler = new StreamHandler($loggerSettings['path'], $loggerSettings['level']);
$logger->pushHandler($handler);
return $logger;
},
PDO::class => function (ContainerInterface $c) {
$settings = $c->get('settings');
$db = [
'dbname' => $settings['db']['name'],
'user' => $settings['db']['username'],
'pass' => $settings['db']['password'],
'host' => $settings['db']['host']
];
$connection = new PDO("mysql:host=" . $db['host'] . ";port=3306;dbname=" . $db['dbname'], $db['user'], $db['pass']);
$connection->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
$connection->setAttribute(PDO::ATTR_DEFAULT_FETCH_MODE, PDO::FETCH_ASSOC);
return $connection;
},
]);
};
My Model Class
namespace App\Application\Models;
use App\Application\Models\DataObjects;
use Psr\Log\LoggerInterface;
use Psr\Container\ContainerInterface;
use DateTime;
use PDO;
class UsersService extends DataObjects
{
protected $db;
public function __construct()
{
}
public function getAll($params)
{
$orderBy = (isset($params['sortdesc']) && empty($params['sortdesc']) === false) ? $params['sortdesc'] . ' DESC' : null;
if ($orderBy === null) {
$orderBy = (isset($params['sortasc']) && empty($params['sortasc']) === false) ? $params['sortasc'] . ' ASC' : '';
}
return $this->loadAll($orderBy);
}
}
