I was worried I'd missed something critical in the manual! References aren't easy to wrap your head around; I, for one, am very happy that I don't need to worry about them nearly as much with PHP5 (syntax is now, "do what I mean"). Interestingly enough, however, the PHP4 behaviour is actually much closer to perl's -- which should have made it easier for me (being a perl programmer), but somehow didn't. -- 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@xxxxxxxxxx | http://vermontbotanical.org -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
