Re: deciperhing oop

PHP 5 will allow your assumption, i.e. $db will resolve to the $db in the class namespace. If you also have a global variable named $db, you can refer to it using main::$db, instead of using the global statement. Pretty slick, if you ask me. By the way, check out PEAR's DB and MDB classes, http://pear.php.net/package-info.php?pacid=46 and http://pear.php.net/package-info.php?pacid=54 Greg -- phpDocumentor http://www.phpdoc.org "Larry Brown" <larry.brown@dimensionnetworks.com> wrote in message news:CBECIONKKLMDDCIKHALJAELMGFAA.larry.brown@dimensionnetworks.com... > Thank you everyone for helping.
