README

Emits a Response to the PHP Server API.

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.

Installation

composer require narrowspark/http-emitter

Use

How to use the SapiEmitter:

<?php

use Narrowspark\HttpEmitter\SapiEmitter;

$response = new \Response();
$response->getBody()->write("some content\n");

$emitter = new SapiEmitter();
$emitter->emit($response);

If you missing the Content-Length header you can use the \Narrowspark\HttpEmitter\Util\Util::injectContentLength static method.

<?php

use Narrowspark\HttpEmitter\Util;

$response = new \Response();

$response = Util::injectContentLength($response);
