Subject: Re: [PHP-DEV] Re: Please test PDO
From: kingwez@gmail.com (Wez Furlong)

That's also something of a hack (PDO core doesn't and shouldn't know
about mysql specific features).

It's better to have a generic mechanism for this, such as the
"interfaces" idea I mentioned a couple of years back.

I don't think there will be time to wedge that into 5.1 though :-/
