How to get filp/whoops to work in Laravel 5.2 or 5.3 - Add this code to your `App\Exceptions\Handler.php` file.

App\Exceptions\Handler.php

/**
 * Create a Symfony response for the given exception.
 *
 * @param  \Exception  $e
 * @return mixed
 */
protected function convertExceptionToResponse(Exception $e)
{
    if (config('app.debug')) {
        $whoops = new \Whoops\Run;
        $whoops->pushHandler(new \Whoops\Handler\PrettyPageHandler);

        return response()->make(
            $whoops->handleException($e),
            method_exists($e, 'getStatusCode') ? $e->getStatusCode() : 500,
            method_exists($e, 'getHeaders') ? $e->getHeaders() : []
        );
    }

    return parent::convertExceptionToResponse($e);
}

Is this work on 5.4? When I use this into test environment it works and the laravel version is 5.4. And I use this to my work environment it doesn't work and the laravel version is 5.4.
And if not how I can use in 5.4?
I really like this so I really want to use in 5.4 :(

Thanks Alex! I'm using Laravel 5.4.30 (PHP 5.6.30 and Apache ) and it works for me. FYI: After the composer require filp/whoops completed, the messages in my command window mentioned I might want to also require whoops/soap so I also did that....doubt it matters to work on 5.4 but just in case.

Great, That worked for me.

Thanks Alex sir ! and I have a question . I have just update my old laravel 5.3 to 5.8 ... so does it work in same way as you said or not ?

Thanks, Sir!
