Thank you for taking the time to write to us, but this is not
a bug. Please double-check the documentation available at
http://www.php.net/manual/ and the instructions on how to report
a bug at http://bugs.php.net/how-to-report.php

so don\'t assign it by reference...

But I don't re-assign "$this"! I re-assign "$obj"! Why I can't do this?

You change $this into a reference here. Thus you still try to change it.
