Get PDO instance or PDO DSN

Hi, as mentioned above, how can i get the PDO instance or the DSN it self? thanks.

From inside a controller:

//resolve a singleton service named 'db' from our dependency injector
$db_service = $this->getShared('db');
//resolve the handler of the DB service (PDO in this case)
$pdo = $db->getInternalHandler();

$sql = $pdo->prepare('select ......');
//so on with regular pdo syntax

Any reason you need to resolve PDO in particular? Phalcon provides a pretty good abstraction on top of PDO which is a lot less verbose than regular PDO. Refer to its syntax here

Hi, Thanks for the reply.. just trying to implement Oauth2.0 server by bshaffer with phalcon and rewrite the code based on its interfaces. here's code from Pdo Storage Constructor

    public function __construct($connection, $config = array())
        if (!$connection instanceof \PDO) {
            if (is_string($connection)) {
                $connection = array('dsn' => $connection);
            if (!is_array($connection)) {
                throw new \InvalidArgumentException('First argument to OAuth2\Storage\Pdo must be an instance of PDO, a DSN string, or a configuration array');
            if (!isset($connection['dsn'])) {
                throw new \InvalidArgumentException('configuration array must contain "dsn"');
            // merge optional parameters
            $connection = array_merge(array(
                'username' => null,
                'password' => null,
            ), $connection);
            $connection = new \PDO($connection['dsn'], $connection['username'], $connection['password']);
        $this->db = $connection;
        // ........
