README

Phalcon is an open source web framework delivered as a C extension for the PHP language providing high performance and lower resource consumption.

Bridge PSR-11 connects the Phalcon container (Phalcon\Container\Container) and the PSR-11 (Psr\Container\ContainerInterface) standard in both directions:

• Container - a PSR-11 container backed by a Phalcon container. Use it wherever a Psr\Container\ContainerInterface is expected.
• Adapter - wraps any PSR-11 container so it can be consumed through the Phalcon container's get() / has() surface.

Installation

You can install the package using composer

composer require phalcon/bridge-psr11

Usage

Container - use a Phalcon container through a PSR-11 interface

Phalcon\Bridge\Psr11\Container is a Psr\Container\ContainerInterface, backed by a Phalcon container. Hand it to any code that expects a PSR-11 container.

use Phalcon\Bridge\Psr11\Container;
use Phalcon\Container\Container as PhalconContainer;

// A configured Phalcon container
$phalcon = new PhalconContainer();
// ... register services on $phalcon ...

$container = new Container($phalcon);

// $container is a Psr\Container\ContainerInterface
if ($container->has('router')) {
    $router = $container->get('router');
}

A missing entry throws Phalcon\Bridge\Psr11\Exception\NotFound (a Psr\Container\NotFoundExceptionInterface); has() never throws.

Adapter - use a PSR-11 container as a Phalcon container

Phalcon\Bridge\Psr11\Adapter wraps a Psr\Container\ContainerInterface and exposes it through the Phalcon container's get() / has() surface. Use it when a PSR-11 container already exists, such as PHP-DI, and it needs to act as a Phalcon container.

use Phalcon\Bridge\Psr11\Adapter;

// Any Psr\Container\ContainerInterface, e.g. PHP-DI
$psr = new DI\Container(/* ... */);

$container = new Adapter($psr);

if ($container->has('service')) {
    $service = $container->get('service');
}

Development

The repository ships a Docker setup for local development and testing. You only need Docker + Docker Compose; the PHP runtime and Phalcon are provided inside the container.

Quick start

docker compose up -d --build
docker compose exec app composer install
docker compose exec app composer test

app is the Compose service name. The running container is bridge-psr11-app (override with PROJECT_PREFIX). It stays up via a sleep infinity keepalive, so you can docker compose exec app <cmd> freely (e.g. composer update).

Choosing the PHP version

The image is built for one PHP version at a time, selected with the PHP_VERSION build arg (default 8.5; supported 8.1–8.5). Because it is a build arg, changing it requires a rebuild (--build):

docker compose up -d --build                  # PHP 8.5 (default)
PHP_VERSION=8.1 docker compose up -d --build  # PHP 8.1
PHP_VERSION=8.4 docker compose up -d --build  # PHP 8.4

The container keeps the same name, so each rebuild replaces the previous one. To run several versions side by side, give each its own Compose project and prefix:

PHP_VERSION=8.1 PROJECT_PREFIX=bridge-psr11-81 docker compose -p bridge-psr11-81 up -d --build
# then: docker exec -w /srv bridge-psr11-81-app composer test

Choosing the backend

The bridge works against either Phalcon runtime, selected with the PHALCON_VARIANT build arg:

docker compose up -d --build                     # package: phalcon/phalcon (v6, default)
PHALCON_VARIANT=ext docker compose up -d --build  # ext: cphalcon C extension (v5)

Tip: drop PHP_VERSION / PHALCON_VARIANT into a .env file in the repo root to avoid prefixing every command — Compose reads it automatically.

Composer scripts

Run them inside the container, e.g. docker compose exec app composer cs:
