Comment (by dd32):

 My initial thought is that something like this could be used:
 {{{
 if ( property_exists( $object, $field ) || isset( $object->$field ) )
 }}}

 That should work in the following scenario's:
  - Property exists (may be null)
  - Property is magic, `__get()` may return null, `__isset()` properly
 handles null values (ie. does isset(), or checks a property exists in the
 child object, or has a static list of magic keys)

 It would not work when:
  - Property is magic, `__get()` returns null, `__isset()` fails to handle
 `null` values, ie. only does an isset() check that doesn't return truthful
 for null fields.
