In what situations would it be beneficial to use a custom ErrorController in PHP frameworks like Zend to handle uncaught Exceptions?

Using a custom ErrorController in PHP frameworks like Zend can be beneficial when you want to handle uncaught Exceptions in a centralized way. This allows you to customize error handling, log errors, display user-friendly error messages, and redirect users to a specific error page. By implementing a custom ErrorController, you can improve the overall user experience and make it easier to troubleshoot and debug errors in your application. 

// Custom ErrorController to handle uncaught Exceptions in Zend Framework

class ErrorController extends Zend_Controller_Action
{
    public function errorAction()
    {
        $errors = $this->_getParam('error_handler');
        
        switch ($errors->type) {
            case Zend_Controller_Plugin_ErrorHandler::EXCEPTION_NO_CONTROLLER:
            case Zend_Controller_Plugin_ErrorHandler::EXCEPTION_NO_ACTION:
                // 404 error
                $this->getResponse()->setHttpResponseCode(404);
                $this->view->message = 'Page not found';
                break;
            default:
                // 500 error
                $this->getResponse()->setHttpResponseCode(500);
                $this->view->message = 'Application error';
                break;
        }
        
        // Log error message
        $logger = new Zend_Log(new Zend_Log_Writer_Stream('path/to/error.log'));
        $logger->log($errors->exception->getMessage(), Zend_Log::ERR);
        
        // Display user-friendly error message
        $this->view->exception = $errors->exception;
    }
}
