This might do it, it might not.

class foo {
  var db;

  function foo() {
    global $_PHPLIB
    include($PHPLIB[libdir]. "/DB_of_choice");
    $var = new DB_SQL
  }
}
$foo->db->query("SELECT bar FROM baz WHERE baz.gnu='gnomovision'");

In theory the Object namespace in php is protected from from the global
namespace so an include() statement in a instanced class should only
affect the namespace inside that particular object, not gloablly, so *in
theory* there shouldn't be any namespace collsions.

<hedge>
I may be grossly misinformed about the way namespaces work, if so, then
please disreagrad and just know that mixing db's in a script is not a too
teribliy good idea in terms of maintainibility
</hedge>
