	)

Dispatch middleware.

Given a route (which contains the handler for given middleware), the $err value passed to $next, $next, and the request and response objects, dispatch a middleware handler.

If $err is non-falsy, and the current handler has an arity of 4, it will be dispatched.

If $err is falsy, and the current handler has an arity of < 4, it will be dispatched.

In all other cases, the handler will be ignored, and $next will be invoked with the current $err value.

If an exception is raised when executing the handler, the exception will be assigned as the value of $err, and $next will be invoked with it.

Parameters

Route	$route
mixed	$err
ServerRequestInterface	$request
ResponseInterface	$response
callable	$next
