New You can do that with PEAR
And still keep it away from the programmers. Create a class that extends DB.php. Wrap the connection method with your own, which checks if you're reading or updating. If you're reading, do it from one of the slaves. Best way is to put a load balancer in front of the slaves so you can dynamically add/remove slaves without interrupting the app. Next best is round-robin or random select within your class.




Wait, you said ADODB. I used DB, not DB_ado, but I assume the above still applies.

Kip Hawley is still an idiot.

New ADODB has a reputation.
Mainly that it's a heavy layer for what it does.

You're right: derive a new class and use that instead makes sense. That's probably what I'll do for that other project.
