Registering an Error Handler for Fatal Errors

This will intercept FatalErrorException errors. The full namespace to this type of error is Symfony\Component\Debug\Exception\FatalErrorException.

App::fatal(function($exception)
{
    die('FATAL ERROR: '.$exception->getMessage());
});

When it doesn't work there's usually just a few reasons:

• php.ini does not have display_startup_errors on
• The error is occurring in part of Laravel's foundation code.
• The error is severe enough that error handling cannot run.

Fatal errors are those defined by PHP to be: E_ERROR, E_CORE_ERROR, E_COMPILE_ERROR, or E_PARSE.

When your application terminates and there was an unhandled exception that caused the termination then Laravel throws a fatal error.
