The above notation is unnecessary when developing in PHP5, as objects in PHP5 are passed by reference by default. However, in PHP4, this was often necessary if you needed to, for instance, store an object in an array or another object (otherwise you got a copy of the object, which means state would then differ between the original and the copy). -- 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
