Error Handlers

A package that includes wrappers for popular error handling services.

Includes an integration library for CakePHP 3.

Requirements

• PHP 5.5+
• Patience

Installation

Usage

You can register the Handler class as a handler of php errors and exceptions.

The registered handler returns false by default. This allows you to chain error handlers such that this package can handle reporting while another library can display user-friendly error messages.

Available Handlers

The following are built-in handlers with their configuration options:

• AirbrakeHandler:: Uses the official airbrake php package.
  • host: (optional | default: api.airbrake.io)
  • projectId: (required | default: null)
  • projectKey: (required | default: null)
• BugsnagHandler: Uses the official bugsnag php package.
  • apiKey: (required | default: null)
• MonologStreamHandler: Uses the monolog StreamHandler.
  • name: (optional | default: error)
  • handlerClass: (optional | default: Monolog\Handler\StreamHandler)
  • stream: (optional | default: log/error.log)
  • level: (optional | default: Monolog\Logger::Warning)
• NewrelicHandler: Uses the newrelic php extension.
• RaygunHandler: Uses the official raygun php package.
  • apiKey: (required | default: null)
• SentryHandler: Uses the official sentry raven php package.
  • dsn: (required | default: null)
  • release: (optional | default: null)

Handler and Exception Modification

Modifying the client handler

Sometimes you may find it useful to modify the client. For instance, it may be necessary to add contextual information to the given client call. To do so, you can set the clientCallback configuration key:

Note that the client should still respond to the existing reporting API provided by the upstream library. You may respond with a proxy library if desired, though returning the initial client is ideal.

$client may be set to null inside of clientCallback if the handler is improperly configured.

Modifying the exception

If necessary, it is possible to modify the exception being used within a particular handler. Changes to the exception will persist only for the duration of that particular handler call.

To do so, set the exceptionCallback configuration key for a particular handler:

You may return another exception or null. In the latter case, the built-in handlers will skip reporting the given exception.

Custom Handlers

Each handler should implement the Josegonzalez\ErrorHandlers\Handler\HandlerInterface. This interface contains a single method:

• PHP 5.x errors will be replaced with wrapper ErrorException instances before sent to the handle method.
• PHP 7.x errors extending Throwable will be replaced with wrapper Josegonzalez\ErrorHandlers\Exception\PHP7ErrorException instances before sent to the handle method.
• PHP Fatal errors will be replaced with wrapper Josegonzalez\ErrorHandlers\Exception\FatalErrorException instances before sent to the handle method.
• PHP Exceptions will be sent in, unmodified.

Custom handlers should extend the provided Josegonzalez\ErrorHandlers\Handler\AbstractHandler class. This gives them the ability to have configuration passed in via the provided ConfigTrait and custom __construct().

CakePHP Usage

You will want to setup at least the following configuration keys in your config/app.php:

• Error.config: Takes the same configuration array as you would give for normal php usage.

Next, configure the provided ErrorHandler classes in your config/bootstrap.php:

Running Tests

Yup, the tests require CakePHP. Pull requests welcome!
