Does PHP error_reporting(0) affect error logging, or just display?

Question

Does error_reporting(0); have any effect on error logging (to file), or does it just suppress on-screen error display?

Thanks.

Answer 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.

Answer 2

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

Answer 3

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.
