Hi, I have a series of nested functions which return a large string (as apposed to working on global string) , is this inefficient? Or is PHP clever enough to just pass a pointer? to simplify $large_string=fn_one(fn_two(fn_three()))); your advice pls -- zzapper Success for Techies and Vim,Zsh tips http://SuccessTheory.com/ -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
