You can't do this with PHP MapScript.  The reason is that the MapScript 
classes are not pure PHP classes, they are just wrappers on top of the 
low-level C structures.  When you assign label objects this way, only 
the PHP wrapper part of the object is copied, but the low-level C 
structure is not modified.  That's the same reason why you need to use 
the set() methods to set class member variables and cannot set them 
directly.
