[OBSOLETE] PSR-7 compatibility is now built into php-pm directly.

PHP-PM PSR-7 Adapter

PSR-7 adapter for use of PSR-7 middleware applications with PHP-PM. See


composer require php-pm/psr7-adapter


PPM bootstraps your application once, and then passes all incoming requests to this instance. This instance needs to be a PSR-7 compatible interface, which means it needs to implement the following interface:

public function __invoke($request, $response, $next = null)

So, to be compatible with this adapter, you need to implement a class that, when instantiated, sets up your application, and implements the __invoke method as described above.

For example, if you use Zend's Stratigility library, your bootstrapper could look like this:

namespace Your\App;

use Zend\Stratigility\MiddlewarePipe;

class Middleware
    protected $pipe;

    public function __construct()
        // Set up the application

        $this->pipe = new MiddlewarePipe;

        $this->pipe->pipe(new MyFirstMiddleware);
        $this->pipe->pipe(new MySecondMiddleware);
        $this->pipe->pipe(new MyThirdMiddleware);

    public function __invoke($request, $response, $next = null)
        $middleware = $this->pipe;
        return $middleware($request, $response, $next);

Starting the server

When starting PPM, pass your middleware as the bootstrapper:

vendor/bin/ppm start --bridge=PHPPM\\Psr7\\Psr7Bridge --bootstrap=Your\\App\\Middleware

Alternatively, first configure PPM to use these options by default, and then start it directly:

vendor/bin/ppm config --bridge=PHPPM\\Psr7\\Psr7Bridge --bootstrap=Your\\App\\Middleware
vendor/bin/ppm start
