The current driver has no option to allow the usage of SSL connections on mysql. I've used the same name params as mysql client.
An example of mysql client usage would be:

mysql --ssl-ca='path_to_ca.pem' --ssl-cert='path_to_client_cert.pem' --ssl-key='path_to_client_key.pem'

refactor secure connection as params

remove space

add space

refactor secure connection

rename method

docs: add ssl params to use in mysqli driver

rename test method

refactor method setSecureConnection

fix bug

add comment to method

remove string escaping

The PDO connection allow the instantiation of the connection even if the dbname
parameter isn't present. This change is there to make sure both behave the same way.

Fixes the warning emitted by mysqli when sqlstate is not set (yet?).

Warning masks actual connection error.

Added flags support for mysqli::real_connect in Mysqli driver. This is necessary if you want to set connection options like compression or SSL encryption.

This PR introduces a new PingableConnection interface and exposes
a ping method on \Doctrine\DBAL\Connection. For drivers where no
ping is supported, a \Doctrine\DBAL\ConnectionException is thrown.

 * push error handling down to when it occurs
 * WIP, as I am unable to trigger false currently

 * move supportedDriverOptions into setDriverOptions
 * make setDriverOptions private
 * support \MYSQLI_SERVER_PUBLIC_KEY on 5.5.0+

 * fix typo
 * remove fluent interface

 * introduced $_supportedDriverOptions to validate what is passed into the object
 * added `setDrivrOptions()` which sets the array and throws exceptions

- Fixed docblocks
- Removed return statements on void methods
- Cleaned up unused private / local variables
- Fixed license issues
- Removed SVN leftovers
- Fixed doctrine-project.org links
- Added line breaks before return statements

Hopefully final fixes. Added phpdoc @inheritdoc where it were missing. Added MysqlConnection::getWrappedResourceHandle(). MysqliStatement::fetchAll() now decide fetch style if none is set, instead of letting fetch() do it on every call.
