Peter,

You probably do not have DBA support compiled into PHP.  That's my guess.
When you compiled PHP, you should have had a line like this when you
configured:  --enable-dba

You can check to see if you did this by creating the following simple page:

<?

echo phpinfo();

?>

At the top of the page outputted, you should see your configure line.  If
you have DBA support, it should also list DBS support somewhere on that
page.

Hope that helps you out some,

Josh Hoover
