Question

I’m trying to setup a new web-application for learning purposes using the newest technologies: apache 2.4, PHP 5.4 and PostgreSQL 9.1

I’ve chosen to develop using Zend Framework 2.

In my main module I have defined this method:

public function getServiceConfiguration() {
    return array(
        'factories' => array(
            'adapter' => function ($sm) {
                $config = $sm->get('config');
                $adapter = new Adapter($config['db']);

                return $adapter;
            }
        ),
    );
}

$config[‘db’] is defined in my autoload/global.php, which contains:

return array(
    'db' => array(
        'driver' => 'PDO',
        'dsn' => 'pgsql:host=localhost;port=5436;user=root;password=myrootpwd',
    )
);

but when I try to call $serviceManager->get(‘adapter’) I get an exception saying:

Fatal error: Uncaught exception ‘Zend\Db\Adapter\Exception\InvalidArgumentException’ with message ‘The supplied or instantiated driver object does not implement Zend\Db\Adapter\Driver\DriverInterface’ in C:\Program Files\626Suite\application\library\Zend\ServiceManager\ServiceManager.php on line 294

EDIT:

I tried to modify the factory as:

public function getServiceConfiguration() {
    return array(
        'factories' => array(
            'adapter' => function ($sm) {
                $config = $sm->get('config');
                $PDO = new \PDO($config['db']['dsn']);
                $adapter = new Adapter($PDO);

                return $adapter;
            }
        ),
    );
}

And I first got an error saying that database "root" does not exists, but after changing my configuration to:

return array(
    'db' => array(
        'driver' => 'PDO',
        'dsn' => 'pgsql:host=localhost;port=5436;dbname=postgres;user=root;password=myrootpwd',
    )
);

I got back to getting the exception I described before.

Answer 1

In the end, I’ve been able to solve this problem too.

The solution was to update the currently used version of Zend Framework 2 from beta4 to the latest master downloaded directly from github.

I suppose there was a problem somewhere in Zend code itself, since now it is working properly without having changed anything in my code or in my settings.
