Hi! > I'm thinking undefined like JavaScript.
Well, in PHP null is closest, but a bit different. I.e. in JS undefined a is an error, but a[0] where a is empty is "undefined". In PHP in both cases you get null and notice, and in both cases you can use isset/empty to check for it. -- Stanislav Malyshev, Software Architect SugarCRM: http://www.sugarcrm.com/ (408)454-6900 ext. 227 -- PHP Internals - PHP Runtime Development Mailing List To unsubscribe, visit: http://www.php.net/unsub.php
