include file in a class with global/parent scope?

Hello, I understand the why $vars is not in the global scope, but i was wondering if there was a way from within the class file to include a file in the parent's scope? i tried ::include('vars.php'), parent::include('vars.php'), but this breaks syntax... Please consider the following three files: 'scope.class.inc' <?php class CScope { public $var = 'class scope\n'; function cinclude($filename) { include('vars.php'); echo "In class $vars\n"; } } ?> 'vars.php' <?php //global $vars;//if this line is uncommented then the desired result is achieved however, i don't want to change all the variables to global scope (this file is includeded in other files where global scoped variables is not desireable). $vars = 'vars.php scope\n'; ?> 'scope.php' <?php include('scope.class.inc'); $object = new CScope; $object->cinclude('vars.php'); echo "In original $vars\n";//$vars is not defined*** ?> Thanks, dK
