Now I happen to know that you (Matthew Weier O'Phinney) are a 'heavy' user
of some/one of the PEAR DB classes because I read the php generals list
alot... I'm guessing your comments below are aimed at functionality
found in PEAR (which DB related class I have no idea) but it's only implied
- might I suggest that, given the fact Patrick calls himself a 'newbie',
that you make it a little more explicit so that he knows what you mean when
you start talking about stuff like DB_FETCHMODE_OBJECT. it would be ashame
if your insight was lost on him because he didn't grok the 'context'.
