I'm trying to get the ini_set("error_reporting",E_ALL); work. No matter what
kind of errors I write I just get blank screen when the script fails. Do I
need to also echo the errors to screen? Or can the error reporting be
disabled by the server admin (my adsl operator)? so that no errors are
printed to screen.
I just set the error reporting at the beginning of the code like:
<?php
ini_set("error_reporting",E_ALL);
etc...
thanks
