## Installation
```bash
composer require nyholm/psr7
```
If you are using Symfony Flex then you get all message factories registered as services.
## Usage
The PSR-7 objects do not contain any other public methods than those defined in
the [PSR-7 specification](https://www.php-fig.org/psr/psr-7/).
### Create objects
Use the PSR-17 factory to create requests, streams, URIs etc.
```php
$psr17Factory = new \Nyholm\Psr7\Factory\Psr17Factory();
$request = $psr17Factory->createRequest('GET', 'http://tnyholm.se');
$stream = $psr17Factory->createStream('foobar');
```
### Sending a request
With [HTTPlug](http://httplug.io/) or any other PSR-18 (HTTP client) you may send
requests like:
```bash
composer require kriswallsmith/buzz
```
```php
$psr17Factory = new \Nyholm\Psr7\Factory\Psr17Factory();
$psr18Client = new \Buzz\Client\Curl($psr17Factory);
$request = $psr17Factory->createRequest('GET', 'http://tnyholm.se');
$response = $psr18Client->sendRequest($request);
```
### Create server requests
The [`nyholm/psr7-server`](https://github.com/Nyholm/psr7-server) package can be used
to create server requests from PHP superglobals.
```bash
composer require nyholm/psr7-server
```
```php
$psr17Factory = new \Nyholm\Psr7\Factory\Psr17Factory();
$creator = new \Nyholm\Psr7Server\ServerRequestCreator(
$psr17Factory, // ServerRequestFactory
$psr17Factory, // UriFactory
$psr17Factory, // UploadedFileFactory
$psr17Factory // StreamFactory
);
$serverRequest = $creator->fromGlobals();
```
### Emitting a response
```bash
composer require laminas/laminas-httphandlerrunner
```
```php
$psr17Factory = new \Nyholm\Psr7\Factory\Psr17Factory();
$responseBody = $psr17Factory->createStream('Hello world');
$response = $psr17Factory->createResponse(200)->withBody($responseBody);
(new \Laminas\HttpHandlerRunner\Emitter\SapiEmitter())->emit($response);
```
## Our goal
This package is currently maintained by [Tobias Nyholm](http://nyholm.se) and
[Martijn van der Ven](https://vanderven.se/martijn/). They have decided that the
goal of this library should be to provide a super strict implementation of
[PSR-7](https://www.php-fig.org/psr/psr-7/) that is blazing fast.
The package will never include any extra features nor helper methods. All our classes
and functions exist because they are required to fulfill the PSR-7 specification.
