# `php-http2`
## Installation

Install with composer:
```bash
$ composer require joopschilder/php-http2
```

## What is this?

A `curl` wrapper for PHP that uses `HTTP/2` to send requests over a single TCP connection.  
  
Provided are:
- The main class `JoopSchilder\Http2\Http2`
- A simple class for requests supporting `curl` options
- A simple class for responses

## What is this not?

A production-ready library.  
I mean, you _are_ of course allowed to use it if you think it's useful.

## Example

There is some example code in `bin/app.php`.  
In it's most basic form, usage of this library might look like this:
```php
use JoopSchilder\Http2\Http2;
use JoopSchilder\Http2\Response;

$http2 = new Http2();

// Might also be an implementation of the ResponseHandler interface
$http2->onResponse(function(Response $response) {
    var_dump($response);
});

// This creates a request with sensible defaults
$request = $http2->createRequest('https://www.twitter.com/');
$request->setOptions([CURLOPT_USERAGENT => 'AppleTV6,2/11.1']);
$http2->addRequest($request);

// Requests are not executed until this method is called
$http2->execute();
```  
It's a good idea to use a different instance of `Http2` for every host you plan to make a request to.

## What's next?

- Add more control to dynamically add requests to an `Http2` instance
- Make an `Http2` instance coupled to a domain (as this is its intended use) 
- Use [`PSR-7`](https://www.php-fig.org/psr/psr-7/) HTTP message interfaces
- Add a factory for requests
