Does error_reporting(0); have any effect on error logging (to file), or does it just suppress on-screen error display?
Thanks.
回答1:
Yes, it affects both.
The error_reporting level defines what levels of errors gets triggered. Whether you log or display those errors are determined by the other settings.
To summarize:
- error_reporting: What levels of errors get triggered.
- display_errors: Whether to show triggered errors in script output.
- log_errors: Whether to write triggered errors to a log.
In essence, setting error_reporting(0) means that you've turned off error reporting, and nothing will be logged to file or output to the screen.

It just suppresses displayed errors. Your ini settings for error logging determine logging levels.

PHP has pretty good docs, check out
http://us.php.net/manual/en/errorfunc.configuration.php#ini.error-reporting for what it does,
http://us.php.net/manual/en/function.error-reporting.php for the runtime function
Its effects depend on where stderr is going.
