The results of this make perfect sense to me -- the references are passed exactly as I would expect. Let me rephrase my question to you: is there a reason to do the initial object assignment using a reference operator using PHP5? I.e., is there a good reason to do this: $foo =& new Foo(); instead of: $foo = new Foo(); I haven't seen any reason to do the former case using PHP5. -- Matthew Weier O'Phinney | WEBSITES: Webmaster and IT Specialist | http://www.garden.org National Gardening Association | http://www.kidsgardening.com 802-863-5251 x156 | http://nationalgardenmonth.org mailto:matthew@garden.org | http://vermontbotanical.org
