I believe the difference between using =& and = is that the former
passes the value by reference, though I've never been clear about the
benefits of using one over the other when it comes to PEAR:DB (the
PEAR:DB documentation uses =& extensively, so presumably it is the
better method).
if you don't pass objects around by reference then you are actually
creating a copy every time you assign it to a different variable or
pass it to a function - normally when you use objects you want all
code that uses an object to be talking to the same object and not copies
thereof.

Good catch:
So I normally do
$results =& $db->query ( "SELECT * FROM table" );
What is the difference between using the & and not using the &.

$results->query('select * from eternityrecords.journal');
Should this not be:
$results = $db->query('select * from eternityrecords.journal');
