FeIn, Thank you for responding. > what did you expect to happen when you call array_walk_recursive? What I don't understand is why it did not append to the string as it walked through each key/value pair. It seems like even though the variable inside the function called by array_walk_recursive has the same name as a global variable, it gets treated as if it only has local scope and nothing done to it applies to the global variable. -- Dave M G -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
