By default extract _ignores_ variables with dots like a.b Even though register_globals should be removed, it does not mean that the default behaviour of extract should be changed. If it's _necessary_ to provide a way to mimic register_globals functionality, a special flag for it should be added, something like EXTR_MIMIC_REGISTER_GLOBALS that will replaces incorrect characters in the variable names with underscrores. In this case BC won't be broken. -- PHP Internals - PHP Runtime Development Mailing List To unsubscribe, visit: http://www.php.net/unsub.php
