|
powerful stacked error handling system.

|

|

## Installing
|
|
If you use Laravel 4, 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 2](https://github.com/oldskool/WhoopsCakephp/tree/cake2),
|
|
[CakePHP 3](https://github.com/oldskool/WhoopsCakephp),
|
|
[Zend Framework 2](https://github.com/ghislainf/zf2-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),
|
|
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/` 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 handers 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.
|
|
|
|
### 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).
