Depends where you have this fragment of code, but possibly the big fat warning box towards the bottom of http://php.net/language.variables.variable? Cheers! Mike -- Thanks for the link Mike, didn't know that. It doesn't say when this was introduced but I'm sure superglobal variable variables must have worked at some stage, because I've got code that once worked but doesn't anymore and it's due to this. There's always a workaround, just not as elegant. Cheers Arno -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
