HTTP for Icicle

Asynchronous, non-blocking HTTP/1.1 client and server.

This library is a component for Icicle that provides an HTTP/1.1 server and client implementations. Like other Icicle components, this library uses Coroutines built from Awaitables and Generators to make writing asynchronous code more like writing synchronous code.

Example

The example below creates a simple HTTP server that responds with Hello, world! to every request.

#!/usr/bin/env php
<?php

require '/vendor/autoload.php';

use Icicle\Http\Message\{BasicResponse, Request, Response};
use Icicle\Http\Server\{RequestHandler, Server};
use Icicle\Socket\Socket;
use Icicle\Loop;

$server = new Server(new class implements RequestHandler {
    public function onRequest(Request $request, Socket $socket)
    {
        $response = new BasicResponse(Response::OK, [
            'Content-Type' => 'text/plain',
        ]);
        
        yield from $response->getBody()->end('Hello, world!');
        
        yield $response;
    }
    
    public function onError($code, Socket $socket)
    {
        return new BasicResponse($code);
    }
});

$server->listen(8080);

Loop\run();
