Error Handler

It's easy to handle error/exception, find error_handler inside project-name/config/app.php, by default it should be like this:

    'error_handler' => Components\Exceptions\Handler::class,

The config above points to the components excception class, let's check that file go to project-name/components/Exceptions/Handler.php.

Now let's dig into that class file, we have two(2) functions which it are report() and render($e).

Under report() function, we're calling the extended parent class, in which we call these PHP Native Functions register_shutdown_function(), set_error_handler() and set_exception_handler().

Under render($e) function, we have plenty of if statement that checks the class instance of variable $e, such example:

        if ($e instanceof AccessNotAllowedException) {
            return (new CsrfHandler)->handle($e);
        }

The code above passed-in the variable $e under CsrfHandler class, which you could also check how it prints out the error.
