Is this > behavior specific to PHP 5? In PHP4 if you don't make use of $this in a class method then it can be used as a static function. PHP4 does not support static class vars, instead you need to use a static function with a static variable. <?php class Auth { function authenticate() { ... } function staticVar( $setValue=null ) { static $myStaticVar = null; if( $setValue !== null ) { $myStaticVar = $setValue; } return $myStaticVar; } } ?> Cheers, Rob. -- .------------------------------------------------------------. | InterJinn Application Framework - http://www.interjinn.com | :------------------------------------------------------------: | An application and templating framework for PHP.
