phpsgi/funk

An implementation of PHPSGI middleware specification

Funk

, _(*1)

Funk is an implementation of PHPSGI. It supports HTTP servers implemented with PHP SAPI (Apache2 mod_php, php-fpm, fastcgi), therefore you can integrate your application with Funk and switch to different HTTP server implementation., _(*2)

PHPSGI and Funk aims to provide lightweight HTTP interfaces, middlewares for web frameworks. It's a bit different from the PSR-7 spec. PHPSGI focuses on the core data structure instead of forcing components to implement the interface requirements., _(*3)

Components

• HTTP server (with event extension or socket_select)
• SAPI support (php-fpm, apache2 php handler servers)
• Middlewares
• Middleware Compositor
• A Simple Mux Builder (integrated with Pux)

Environment

// This creates $env array from $_SERVER, $_REQUEST, $_POST, $_GET ... 
$env = Environment::createFromGlobals();

Application

$app = function(array & $environment, array $response) {
    return [ 200, [ 'Content-Type' => 'text/plain' ], 'Hello World' ];
};

Responder

SAPIResponder

You can integrate your application with SAPIResponder to support Apache2 php handler / php-fpm / fastcgi., _(*4)

use Funk\Responder\SAPIResponder;

$fd = fopen('php://output', 'w');
$responder = new SAPIResponder($fd);
$responder->respond([ 200, [ 'Content-Type: text/plain' ], 'Hello World' ]);
fclose($fd);

use Funk\Responder\SAPIResponder;

$env = Environment::createFromGlobals();
$app = function(array & $environment, array $response) {
    return [ 200, [ 'Content-Type' => 'text/plain' ], 'Hello World' ];
};
$fd = fopen('php://output', 'w');
$responder = new SAPIResponder($fd);
$responder->respond($app($env, []));
fclose($fd);

Middleware

• Funk\Middleware\ContentNegotiationMiddleware
• Funk\Middleware\CORSMiddleware
• Funk\Middleware\GeocoderMiddleware
• Funk\Middleware\HeadMiddleware
• Funk\Middleware\TryCatchMiddleware
• Funk\Middleware\XHProfMiddleware
• Funk\Middleware\XHTTPMiddleware

use Funk\Environment;
use Funk\Middleware\TryCacheMiddleware;

$app = function(array $environment, array $response) {
    return [ 200,  ['Content-Type' => 'text/html' ], 'Hello World' ];
};
$middleware = new TryCatchMiddleware($app);


$env = Environment::createFromGlobals();
$response = $middleware($env, [200, [], []]);

Testing XHProf Middleware

Define your XHPROF_ROOT in your phpunit.xml, you can copy phpunit.xml.dist to phpunit.xml, for example:, _(*5)

  <php>
    <env name="XHPROF_ROOT" value="/Users/c9s/src/php/xhprof"/>
  </php>
