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. ## Features - 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](docs/Open%20Files%20In%20An%20Editor.md) - Includes handlers for different response formats (JSON, XML, SOAP) - Easy to extend and integrate with existing libraries - Clean, well-structured & tested code-base ## Sponsors <a href="https://blackfire.io/docs/introduction?utm_source=whoops&amp;utm_medium=github_readme&amp;utm_campaign=logo"><img src="https://i.imgur.com/zR8rsqk.png" alt="Blackfire.io" width="254" height="64"></a> ## Installing If you use Laravel 4, Laravel 5.5+ or [Mezzio](https://docs.mezzio.dev/mezzio/), you already have Whoops. There are also community-provided instructions on how to integrate Whoops into [Silex 1](https://github.com/whoops-php/silex-1), [Silex 2](https://github.com/texthtml/whoops-silex), [Phalcon](https://github.com/whoops-php/phalcon), [Laravel 3](https://gist.github.com/hugomrdias/5169713#file-start-php), [Laravel 5](https://github.com/GrahamCampbell/Laravel-Exceptions), [CakePHP 3](https://github.com/dereuromark/cakephp-whoops/tree/cake3), [CakePHP 4](https://github.com/dereuromark/cakephp-whoops), [Zend 2](https://github.com/ghislainf/zf2-whoops), [Zend 3](https://github.com/Ppito/zf3-whoops), [Yii 1](https://github.com/igorsantos07/yii-whoops), [FuelPHP](https://github.com/indigophp/fuel-whoops), [Slim](https://github.com/zeuxisoo/php-slim-whoops/), [Pimple](https://github.com/texthtml/whoops-pimple), [Laminas](https://github.com/Ppito/laminas-whoops), or any framework consuming [StackPHP middlewares](https://github.com/thecodingmachine/whoops-stackphp) or [PSR-7 middlewares](https://github.com/franzliedke/whoops-middleware). If you are not using any of these frameworks, here's a very simple way to install: 1. Use [Composer](http://getcomposer.org) to install Whoops into your project: ```bash composer require filp/whoops ``` 1. Register the pretty handler in your code: ```php $whoops = new \Whoops\Run; $whoops->pushHandler(new \Whoops\Handler\PrettyPageHandler); $whoops->register(); ``` For more options, have a look at the **example files** in [`examples/`](./examples) to get a feel for how things work. Also take a look at the [API Documentation](docs/API%20Documentation.md) and the list of available handlers below. 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 `Run` constructor. You may also collect the HTML generated to process it yourself: ```php $whoops = new \Whoops\Run; $whoops->allowQuit(false); $whoops->writeToOutput(false); $whoops->pushHandler(new \Whoops\Handler\PrettyPageHandler); $html = $whoops->handleException($e); ``` ### Available Handlers **whoops** currently ships with the following built-in handlers, available in the `Whoops\Handler` namespace: - [`PrettyPageHandler`](https://github.com/filp/whoops/blob/master/src/Whoops/Handler/PrettyPageHandler.php) - Shows a pretty error page when something goes pants-up - [`PlainTextHandler`](https://github.com/filp/whoops/blob/master/src/Whoops/Handler/PlainTextHandler.php) - Outputs plain text message for use in CLI applications - [`CallbackHandler`](https://github.com/filp/whoops/blob/master/src/Whoops/Handler/CallbackHandler.php) - 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 `Whoops\Run::pushHandler` - [`JsonResponseHandler`](https://github.com/filp/whoops/blob/master/src/Whoops/Handler/JsonResponseHandler.php) - Captures exceptions and returns information on them as a JSON string. Can be used to, for example, play nice with AJAX requests. - [`XmlResponseHandler`](https://github.com/filp/whoops/blob/master/src/Whoops/Handler/XmlResponseHandler.php) - 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](https://github.com/whoops-php/soap). ## Authors This library was primarily developed by [Filipe Dobreira](https://github.com/filp), and is currently maintained by [Denis Sokolov](https://github.com/denis-sokolov). A lot of awesome fixes and enhancements were also sent in by [various contributors](https://github.com/filp/whoops/contributors). Special thanks to [Graham Campbell](https://github.com/GrahamCampbell) and [Markus Staab](https://github.com/staabm) for continuous participation.
