php in silent mode

[gilas]

Hi Folks
I need to configure php in silent mode so that error messages are not viewed on the browser.
Then my simple question is: for each site configured there is a php.ini to modify?!? Moreover: if I suppress all error-messages the errors are addressed to each error-log for each virtual server?

Thank you very much in anticipation!

There is only one php.ini for all sites. You may search for the php.ini file with the command:

locate php.ini

The correct file is in a subdirectory of /etc/, e.g. /etc/php5/apache/php.ini
