error_reporting(0)..

I am attempting to write my own little error-logging function... however, for some reason, whatever I do I can not seem to override the error display setting on the server. Starting at the most simple thing, you should think that when you write . <? Error_reporting(0); ?> . should pretty much stop every error message eventually generated on the production server. But it wont. The only way I can shut off the error messages, is to set "display_errors = Off" in PHP.INI . Now, this means I can track i.e. NOTICE errors, but parse-errors will show nonetheless. My wish is that whatever error the system outputs, I would like to be able to deal with them my very own custom way. Anybody got a good idea of how I can successfully switch off these pesky error messages on runtime level and then trap them all? Rob.
