Say I am retrieving an object from a function...

The object really has no distinguishable type as far as my code can
tell (It's from a SOAP function, the objects returned do not have
different types).

$client = new SoapClient("/geocoder.wsdl");

// Retrieve the address coordinates
$result = $client->geocode($address);

Now, there could be two "types" of objects returned, with two distinct
sets of members.

say one type has a member "prefix" and one has a member "prefix1"

my question is, how can I figure out which type the function has
returned? I don't think I can do isset( ) to test if a member exists.
