What directive in the php.ini file do i need to change so that when php outputs errors it doesn't output the physicaly mapped path of the php file in question. I would rather have it output something like..

www.hosting.com/membername/phpfile.php

Insead of:

f:\home\membername\phpfile.php

You got to set php error pages your self.

look at webeserver information

yes, definitely set a custom error message in apache.
