On a smaller project, everything goes fine.

It does some wrong changes:

    -        $query['params'] = (array) $query['params'];
    +        $query['params'] =(array) $query['params'];

@fabpot Nice find, fixed now. Thanks.

One more:

    - 'second' => (string)(int)$dateTime->format('s'),
    + 'second' => (string) (int)$dateTime->format('s'),

Notice that it fails to add a space after the `int` type hint.

@fabpot Fixed, thanks.

There is still a problem:

    -     * @param int   $type  The type to convert. Can be TYPE_DOUBLE (float) or TYPE_INT32 (int)
    -     *
    +     * @param int   $type  The type to convert. Can be TYPE_DOUBLE (float) or TYPE_INT32 (int) *

After fixing this last bug, can you squash your commits before I merge this PR? Thanks.
