You fake it by declaring them private and writing a get_foo() method for each one. Done this way it it is tedious and ugly, but by overloading member access with the __get( $name ) method, you can achieve the same functionality with fewer lines of code and a cleaner interface to client classes. See under overloading in http://www.php.net/zend-engine-2.php for examples. -- __o Alex Farran _`\<,_ Analyst / Programmer (_)/ (_) www.alexfarran.com -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
