MachineLegacyBridgeBundle

What is this?

This bundle generates a symfony route from each .php file on the given legacy_path folder, so you can access your old scripts through the symfony frontcontroller as they where actually present. Additionally the wrapper injects the symfony DI-Container into $_SERVER['SYMFONY_CONTAINER'], so you can slowly refactor the legacy app, by extracting services into symfony services but use them in the legacy code, as well.

Inspired from Modernizing with Symfony given by @derrabus

Installation

composer require machine-rc/legacy-bridge-bundle

Configuration

In your config.yml place:

machine_legacy_bridge:
    legacy_path:    '/full/path/to/my/legacy/project/files'
    # optional prepend script (see http://php.net/manual/en/ini.core.php#ini.auto-prepend-file)
    prepend_script: '/full/path/to/my/legacy/autoPrependFile.php' # can be ommited
    # optional append script (see http://php.net/manual/en/ini.core.php#ini.auto-append-file)
    append_script:  '/full/path/to/my/legacy/autoAppendFile.php' # can be ommited

Legacy route loader

• Implement generator class extending Machine\LegacyBridgeBundle\Factory\LegacyRouteGeneratorInterface. It should parse file and generate route as you see fit.
• Update services.yaml to load your generator

    Machine\LegacyBridgeBundle\Factory\LegacyRouteFactory:
        calls:
            - [ addGenerator, [ '@App\Factory\LegacyTVSRouteGenerator'] ]

Legacy route processor

• Implement processor class extending Machine\LegacyBridgeBundle\Factory\LegacyRouteProcessorInterface. It should provide closure that executes legacy controller loop
• Update services.yaml to set your processor

    Machine\LegacyBridgeBundle\Factory\LegacyRouteFactory:
        calls:
            - [ setRouteProcessor, [ '@App\Factory\LegacyTVSRouteProcessor'] ]

On the legacy app

<?php // e.g. my-old-stuff.php
/** @var \Symfony\Component\DependencyInjection\ContainerInterface $container */
$container = $_SERVER['SYMFONY_CONTAINER'];
$myService = $container->get('my.service.id');
