ummm...php 3 (which has oop capabilities too) and php 5 are cosmetically
*identicle*...they both look like a scripting language resembling c (like a
lot other scripting languages). anyway...
the ONLY time reflection allows you to change a private member of a class
object is when the caller is within appropriate scope...i.e. friend or
subordinate/nested class. outside of that, reflection NEVER acts as you
intend, even in c++. jerry is correct. and, as php doesn't support friend or
nested classes, you are sol. sorry. you are limited to hacking to get values
of variables that are private...this leaves out, entirely, the possibility
of discovering 'hidden' interfaces/methods that should remain
encapsulated...i.e. private. the only other hack i haven't tried is to
inherit from the object you're trying to hack and then reflecting on the
base object from there. that may be your workaround for those interfaces.
btw, what are you trying to accomplish?
