read_only=true; ... after the value is set. Switch off all the 'setter' magic once the object has been created, but I still see a problem where this only really works with simple values? If I've created a more complex object, while it's 'value' may need to be fixed, how it's displayed may involve setting alternative defaults, so one still needs to be able to set other variables in the object. -- Lester Caine - G8HFL ----------------------------- Contact - http://lsces.co.uk/wiki/?page=contact L.S.Caine Electronic Services - http://lsces.co.uk EnquirySolve - http://enquirysolve.com/ Model Engineers Digital Workshop - http://medw.co.uk Rainbow Digital Media - http://rainbowdigitalmedia.co.uk -- PHP Internals - PHP Runtime Development Mailing List To unsubscribe, visit: http://www.php.net/unsub.php
