CodeIgniter not logging all PHP errors?

[eluser]FireStarter[/eluser]
Does anyone have any idea why CI doesn't appear to log any PHP errors apart from Notice errors? My error reporting is set to E_ALL in index.php. For example I throw a random nonexisting function() into my code and this does not get logged. I understand that fatal errors cannot be logged via CI but what about the others? I can't seem to find any bugs anywhere to explain this.

Ideally, I would like to disable CI's overriding of handling PHP errors - I normally have PHP itself log all errors to a file. However, I don't want to hack the core. Is it possible to stop CI from overriding PHP error handling without hacking the core?

Thanks

read about error handling and that should answer all your questions.

I wouldn't recommend disabling CI's error handling.

Some errors can't (and thus, won't) be handled by the error handler. From http://us.php.net/manual/en/function.set...andler.php:

The following error types cannot be handled with a user defined function: E_ERROR, E_PARSE, E_CORE_ERROR, E_CORE_WARNING, E_COMPILE_ERROR, E_COMPILE_WARNING, and most of E_STRICT raised in the file where set_error_handler() is called.
