I doubt anyone is going to write a php version of that function for you. given that you are not the server admin then someone else must be, go to that person and ask them to run the relevant pecl command: pecl install stats if they won't get another hoster. regardless you can still develop with that extension on your local machine. If you really need such a function/extension then you should be able to convince the client that it's less effort to find suitable hosting than it is to waste time reinventing a, potentially complex, wheel. >
