Creating and filling database from a Controller (Symfony 2, Doctrine) - mysql

Question

I am trying to create an installation Bundle for my Symfony 2.2.3 application.
Therefore I want to drop/create a database (mysql) and then create the schema via Controller Actions.
My Code:
$kernel = $this->get('kernel');
$application = new \Symfony\Bundle\FrameworkBundle\Console\Application($kernel);
$application->setAutoExit(false);
// drop old database
$options = array('command' => 'doctrine:database:drop', '--force' => true);
$application->run(new \Symfony\Component\Console\Input\ArrayInput($options));
// create new database
$options = array('command' => 'doctrine:database:create');
$result = $application->run(new \Symfony\Component\Console\Input\ArrayInput($options));
// check if database:create was successful, then create schema
if($result == 0) {
$options = array('command' => 'doctrine:schema:create');
$result = $application->run(new \Symfony\Component\Console\Input\ArrayInput($options));
}
database:drop and database:create work fine (both commands return 0), but creating the schema then fails.
However, when I comment the first 2 commands out so that only doctrine:schema:create will be executed (if clause removed, of course) and reload the page without changing anything else the database schema will be created properly.
Can anyone tell me what the problem is?

This code works (Symfony 2.7)
use Symfony\Bundle\FrameworkBundle\Console\Application;
use Symfony\Component\Console\Input\ArrayInput;
/**
* #Route("/resetDB", name="adminResetDB")
*/
public function resetDBAction()
{
$application = new Application($this->get('kernel'));
$application->setAutoExit(false);
// Drop old database
$options = array('command' => 'doctrine:database:drop', '--force' => true);
$application->run(new ArrayInput($options));
// Make sure we close the original connection because it lost the reference to the database
$this->getDoctrine()->getManager()->getConnection()->close();
// Create new database
$options = array('command' => 'doctrine:database:create');
$application->run(new ArrayInput($options));
// Update schema
$options = array('command' => 'doctrine:schema:update','--force' => true);
$application->run(new ArrayInput($options));
// Loading Fixtures, --append option prevent confirmation message
$options = array('command' => 'doctrine:fixtures:load','--append' => true);
$application->run(new ArrayInput($options));
return $this->redirect($this->generateUrl('index'));
}
