DB_DataObject

Hi, I'm trying to get my head around DB_DataObject. I've implemented the sample code in the documentation, and it works very nicelly indeed. What I'm curious about is, when exactly does the database connection happen? Does it open a new connection each time an sql statement is required (such as when call $person->get()). If so, how is this for efficiency? Previously my app was opening a single connection for all the queries required for that php process. Secondly, is there any way to make it use a specific pear DB object? I'd like to be able to use these DB_DataObject(s) in conjuction with unit tests, and it might be nice to be able to pass in a 'mock' database object. regards, Craig -- Craig Ambrose Freelance Web Developer http://www.portallus.com/people/craigambrose/
