The available emitter implementations are.

```
- `Narrowspark\HttpEmitter\SapiEmitter`
- `Narrowspark\HttpEmitter\SapiStreamEmitter`.

```

> **Note:** each use the native PHP functions `header()` and `echo` to emit the response.

> **Note:** if headers have been sent, or the output buffer exists, and has a non-zero length, the emitters raise an exception, as mixed PSR-7 / output buffer content creates a blocking issue.
>
> If you are emitting content via `echo`, `print`, `var_dump`, etc., or not catching PHP errors / exceptions, you will need to either fix your app to always work with a PSR-7 response. Or provide your own emitters that allow mixed output mechanisms.
