PHP Interface Zend\Stratigility\ErrorMiddlewareInterface

Error middleware is essentially the same as the MiddlewareInterface, with one key distinction: it has an additional argument prepended, representing an error condition. Next will skip error middleware if called without an error; conversely, if called with an error, it will skip normal middleware. Error middleware does something with the arguments passed, and then either returns a response, or calls $out, with or without the error.

Deprecation: since 1.3.0; will be removed with 2.0.0. Please see https://docs.zendframework.com/zend-stratigility/migration/to-v2/ for more information on how to update your code for forwards compatibility.
