It isn't a pointer. It is a reference which you should think of as a symbol table alias. A pointer, at least by my definition, is a memory address. In PHP it isn't a memory address, just another entry in the symbol table that references the same data as another symbol. -Rasmus -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
