PHP errors for cool kids
whoops is an error handler framework for PHP. Out-of-the-box, it provides a pretty error interface that helps you debug your web projects, but at heart it's a simple yet powerful stacked error handling system.
- Flexible, stack-based error handling
- Stand-alone library with (currently) no required dependencies
- Simple API for dealing with exceptions, trace frames & their data
- Includes a pretty rad error page for your webapp projects
- Includes the ability to open referenced files directly in your editor and IDE
- Includes handlers for different response formats (JSON, XML, SOAP)
- Easy to extend and integrate with existing libraries
- Clean, well-structured & tested code-base
If you use Laravel 4, Laravel 5.5+ or Mezzio, you already have Whoops. There are also community-provided instructions on how to integrate Whoops into Silex 1, Silex 2, Phalcon, Laravel 3, Laravel 5, CakePHP 3, CakePHP 4, Zend 2, Zend 3, Yii 1, FuelPHP, Slim, Pimple, Laminas, or any framework consuming StackPHP middlewares or PSR-7 middlewares.
If you are not using any of these frameworks, here's a very simple way to install:
Use Composer to install Whoops into your project:
composer require filp/whoops
Register the pretty handler in your code:
$whoops = new \Whoops\Run; $whoops->pushHandler(new \Whoops\Handler\PrettyPageHandler); $whoops->register();
You may also want to override some system calls Whoops does. To do that, extend
Whoops\Util\SystemFacade, override functions that you want and pass it as the argument to the
You may also collect the HTML generated to process it yourself:
$whoops = new \Whoops\Run; $whoops->allowQuit(false); $whoops->writeToOutput(false); $whoops->pushHandler(new \Whoops\Handler\PrettyPageHandler); $html = $whoops->handleException($e);
whoops currently ships with the following built-in handlers, available in the
PrettyPageHandler- Shows a pretty error page when something goes pants-up
PlainTextHandler- Outputs plain text message for use in CLI applications
CallbackHandler- Wraps a closure or other callable as a handler. You do not need to use this handler explicitly, whoops will automatically wrap any closure or callable you pass to
JsonResponseHandler- Captures exceptions and returns information on them as a JSON string. Can be used to, for example, play nice with AJAX requests.
XmlResponseHandler- Captures exceptions and returns information on them as a XML string. Can be used to, for example, play nice with AJAX requests.
You can also use pluggable handlers, such as SOAP handler.
This library was primarily developed by Filipe Dobreira, and is currently maintained by Denis Sokolov. A lot of awesome fixes and enhancements were also sent in by various contributors. Special thanks to Graham Campbell and Markus Staab for continuous participation.
