fatal errors with extending PDO and interface usage

[dasmfm]

Got the following problem with fresh deb-package and latest Doctrine DBAL.

It has following class, extending PDO extension.

class PDOConnection extends PDO implements Connection
{
    /**
     * @param string      $dsn
     * @param string|null $user
     * @param string|null $password
     * @param array|null  $options
     */
    public function __construct($dsn, $user = null, $password = null, array $options = null)
    {
        parent::__construct($dsn, $user, $password, $options);
        $this->setAttribute(PDO::ATTR_STATEMENT_CLASS, array('Doctrine\DBAL\Driver\PDOStatement', array()));
        $this->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
    }
}

Connection interface has following method:

    /**
     * Prepares a statement for execution and returns a Statement object.
     *
     * @param string $prepareString
     *
     * @return \Doctrine\DBAL\Driver\Statement
     */
    function prepare($prepareString);

This method exists in PDO extension, but doesn't exists in PDOConnection class.

So, hhvm throws fatal error (while php works fine):

HipHop Fatal error: Declaration of Doctrine\DBAL\Driver\PDOConnection::prepare() must be compatible with that of Doctrine\DBAL\Driver\Connection::prepare() in /home/dasmfm/doctrine-demo/vendor/doctrine/dbal/lib/Doctrine/DBAL/Driver/PDOConnection.php on line 30

You should apply this patch to DBAL because it is still not merged: doctrine/dbal#373.

@javer, thanks for a solution.
Hope doctrine developers will PR that soon.

Thanks for reporting this. Closing as external as this is the doctrine issue @javer mentions above.
