Project Notice ----------------- [](#1-project-notice) > **Please Note:** This project is not associated with the original Symfony project, SensioLabs, or Fabien Potencier beyond attribution. It is an independent, 7x + community-driven continuation of the Symfony 2.8.52 codebase, stewarded and evolved by [7x (se7enx.com)](https://se7enx.com/) to support PHP 8.x in production. The upstream Symfony source is MIT-licensed; 7x Prime honours that licence by publishing the full source on GitHub. --- 2. Project Status ----------------- [](#2-project-status) The Symfony 2.8.52 codebase was the final upstream release of the Symfony 2.x line. Thousands of production applications built on this component library remained in active use because the architecture — a composable component system, powerful routing, full DI container, and Twig templating — remained sound and productive long after the upstream EOL. **7x Prime (v2.9)** is the first release branch that brings this codebase fully into the PHP 8.x era. ItemStatusUpstream baseSymfony 2.8.52 (last upstream release)Branch`2.9`PHP^8.0 — tested on **PHP 8.5.6**Twigse7enxweb/twig ~1.34|~2.4LicenseMITWork in the `2.9` branch focuses on: - PHP 8.0 through PHP 8.5 full compatibility and PHPUnit test suite passing - Security hardening: SameSite cookies, CRLF-injection protection, YAML object injection prevention - Composer package manager integration - Documentation and developer experience improvements --- 3. Who is 7x ------------ [](#3-who-is-7x) [7x](https://se7enx.com/) is a North American web software corporation with over 24 years of experience building and maintaining PHP web applications and content platforms. Previously known as Brookins Consulting, 7x took on stewardship of the Symfony 2.8.52 codebase to ensure that the many applications built on it can continue to run on modern, supported PHP versions. 7x offers: - Commercial PHP 8.x upgrade consulting for Symfony 2.x applications - Hosting and infrastructure for PHP 8.x projects - Custom development, migrations, and training - Open-source community stewardship --- 4. What is 7x Prime? -------------------- [](#4-what-is-7x-prime) 7x Prime is a **component library and full-stack PHP framework** forked from Symfony 2.8.52. It retains the original MVC architecture, routing engine, form system, security component, console toolkit, and Twig templating while adding: - Full PHP 8.0–8.5.6 compatibility (no deprecations, no fatal errors). - Security hardening: SameSite cookies, CRLF-injection protection, YAML object injection prevention, hardened session defaults. - A clean composer package (`se7enxweb/prime`) without obsolete polyfills. --- 5.

Building Pages, Routes, and DB Results ------------------------------------------ [](#10-building-pages-routes-and-db-results) See [INSTALL.md](INSTALL.md) for full step-by-step instructions. Below is the three-minute version. ### Define a route (YAML) [](#define-a-route-yaml) ``` # app/config/routing.yml homepage: path: / defaults: { _controller: AppBundle:Default:index } blog_show: path: /blog/{slug} defaults: { _controller: AppBundle:Blog:show } requirements: slug: "[a-z0-9\-]+" ``` ### Write the controller [](#write-the-controller) ``` namespace AppBundle\Controller; use Symfony\Bundle\FrameworkBundle\Controller\Controller; use Symfony\Component\HttpFoundation\Request; class BlogController extends Controller { public function showAction(Request $request, string $slug) { $post = $this->getDoctrine() ->getRepository('AppBundle:Post') ->findOneBy(['slug' => $slug]); if (!$post) { throw $this->createNotFoundException('Post not found'); } return $this->render('blog/show.html.twig', ['post' => $post]); } } ``` ### Render with Twig [](#render-with-twig) ``` {# app/Resources/views/blog/show.html.twig #} {% extends 'base.html.twig' %} {% block title %}{{ post.title }}{% endblock %} {% block body %} {{ post.title }} {{ post.body }} {% endblock %} ``` --- 11. Your First Bundle --------------------- [](#11-your-first-bundle) A **Bundle** is the primary extension point in 7x Prime — a self-contained plugin that contributes routes, controllers, Twig templates, services, Doctrine entities, console commands, and more to the application. ### 11.1 Generating the Scaffold [](#111-generating-the-scaffold) ``` php bin/console generate:bundle ``` Answer the interactive prompts: PromptExample valueBundle namespace`Acme/BlogBundle`Bundle name`AcmeBlogBundle`Target directory`src/`Configuration format`yml`This creates: ``` src/Acme/BlogBundle/ ├── AcmeBlogBundle.php ← bundle class (registers itself) ├── Controller/ │ └── DefaultController.php ← starter controller ├── DependencyInjection/ │ ├── AcmeBlogExtension.php ← loads services.yml into the DI container │ └── Configuration.php ← config tree definition (optional) ├── Resources/ │ ├── config/ │ │ ├── routing.yml ← bundle-local route definitions │ │ └── services.yml ← service definitions │ └── views/ │ └── Default/ │ └── index.html.twig ← starter template └── Tests/ └── Controller/ └── DefaultControllerTest.php ``` ### 11.2 Registering the Bundle [](#112-registering-the-bundle) Add the bundle to `app/AppKernel.php`: ``` // app/AppKernel.php public function registerBundles(): array { $bundles = [ // … core bundles … new Acme\BlogBundle\AcmeBlogBundle(), ]; return $bundles; } ``` Mount its routes in `app/config/routing.yml`: ``` acme_blog: resource: "@AcmeBlogBundle/Resources/config/routing.yml" prefix: /blog ``` ### 11.3 Adding a Service [](#113-adding-a-service) Define services in `Resources/config/services.yml`: ``` services: acme_blog.post_manager: class: Acme\BlogBundle\Service\PostManager arguments: - "@doctrine.orm.entity_manager" ``` Inject it into a controller via `$this->get()` or constructor injection: ``` namespace Acme\BlogBundle\Controller; use Symfony\Bundle\FrameworkBundle\Controller\Controller; use Symfony\Component\HttpFoundation\Response; class BlogController extends Controller { public function indexAction(): Response { $posts = $this->get('acme_blog.post_manager')->findLatest(10); return $this->render('@AcmeBlog/Blog/index.html.twig', ['posts' => $posts]); } } ``` ### 11.4 Customising Templates [](#114-customising-templates) **Override a bundle template** by copying it into `app/Resources/`: ``` app/Resources/ └── AcmeBlogBundle/ └── views/ └── Blog/ └── index.html.twig ← overrides @AcmeBlog/Blog/index.html.twig ``` Twig's lookup order: `app/Resources/BundleName/views/` first, then `src/Bundle/Resources/views/`. Any file placed under `app/Resources/` wins automatically — no configuration required. **Extend the global base layout** using Twig block inheritance: ``` {# src/AcmeBlogBundle/Resources/views/Blog/index.html.twig #} {% extends 'base.html.twig' %} {% block title %}Blog{% endblock %} {% block stylesheets %} {{ parent() }} {% endblock %} {% block body %} {% for post in posts %} {{ post.title }} {{ post.excerpt }} Read more {% endfor %} {% endblock %} ``` **Publish bundle assets** (CSS, JS, images) to `web/bundles/`: ``` php bin/console assets:install --symlink web/ ``` This symlinks `src/AcmeBlogBundle/Resources/public/` → `web/bundles/acmeblog/`, making files available at `/bundles/acmeblog/css/blog.css`. ### 11.5 Full Bundle Directory Reference [](#115-full-bundle-directory-reference) ``` src/Acme/BlogBundle/ ├── AcmeBlogBundle.php ├── Command/ ← console commands (auto-discovered) │ └── ImportPostsCommand.php ├── Controller/ ← HTTP controllers │ └── BlogController.php ├── DependencyInjection/ ← DI extension + optional configuration tree │ ├── AcmeBlogExtension.php │ └── Configuration.php ├── Entity/ ← Doctrine entities │ └── Post.php ├── Form/ ← form type classes │ └── PostType.php ├── Repository/ ← Doctrine entity repositories │ └── PostRepository.php ├── Resources/ │ ├── config/ │ │ ├── doctrine/ ← Doctrine XML/YAML mapping (if not using annotations) │ │ ├── routing.yml │ │ ├── routing_dev.yml │ │ └── services.yml │ ├── public/ ← static assets published to web/bundles/acmeblog/ │ │ ├── css/ │ │ └── js/ │ ├── translations/ ← XLIFF / YAML translation catalogues │ │ └── messages.en.yml │ └── views/ ← Twig templates │ ├── Blog/ │ │ ├── index.html.twig │ │ └── show.html.twig │ └── layout.html.twig ← optional bundle-level base layout ├── Service/ ← business-logic service classes │ └── PostManager.php ├── Tests/ ← PHPUnit tests mirroring src/ structure │ ├── Controller/ │ └── Service/ └── Validator/ ← custom constraint classes (optional) └── Constraint/ ``` --- 12.

PHPUnit 11 Test Suite ------------------------- [](#18-phpunit-11-test-suite) 7x Prime ships a complete test suite covering every component, bridge, and bundle in the framework, verified to pass with **PHPUnit 11.5** on **PHP 8.5.6** — zero errors, zero failures, zero warnings, and zero framework-attributed deprecations. ### Test Suite Status [](#test-suite-status) MetricResultPHP version8.5.6PHPUnit version11.5.55Test errors0Test failures0Deprecations (framework)0Warnings0Notices0Tests0 incomplete (8 genuine upstream TODO markers, accepted)### Requirements [](#requirements) PHPUnit 11 requires **PHP 8.1 or higher** and is **not bundled** in `vendor/`. Install it globally (recommended) or as a project dev dependency: ``` # Global install — available as `phpunit` in any project composer global require phpunit/phpunit ^11 # Or as a dev dependency in this project composer require --dev phpunit/phpunit ^11 ``` ### Running the Full Suite [](#running-the-full-suite) ``` # Using globally-installed phpunit (fastest) php /root/.config/composer/vendor/bin/phpunit --no-coverage -c phpunit.xml.dist # Using the project wrapper script (delegates to global phpunit) ./phpunit -c phpunit.xml.dist --no-coverage ``` ### Running a Subset [](#running-a-subset) ``` # Single component directory ./phpunit -c phpunit.xml.dist src/Symfony/Component/HttpFoundation/ ./phpunit -c phpunit.xml.dist src/Symfony/Component/Routing/ ./phpunit -c phpunit.xml.dist src/Symfony/Component/Form/ # Single test class (by class name) ./phpunit -c phpunit.xml.dist --filter RequestTest # Single test method ./phpunit -c phpunit.xml.dist --filter "RequestTest::testGetMethod" # Pattern match across all test classes ./phpunit -c phpunit.xml.dist --filter "/testGet.*Route/" ``` ### Displaying Deprecations, Warnings, and Notices [](#displaying-deprecations-warnings-and-notices) ``` # Show all PHP 8.x notices, deprecations, and warnings during the run php /root/.config/composer/vendor/bin/phpunit \ --no-coverage \ --display-deprecations \ --display-warnings \ --display-notices \ -c phpunit.xml.dist ``` ### PHPUnit 11 — Key Differences from PHPUnit 4–9 [](#phpunit-11--key-differences-from-phpunit-49) PHPUnit 11 uses **PHP 8 native attributes** in place of docblock annotations. Both styles are accepted in 7x Prime's own test files, but attributes are preferred in new code: ``` // Old style — PHPUnit 4–9 docblock annotations (still parsed but deprecated) /** * @dataProvider valuesProvider * @group integration */ public function testProcess($input, $expected): void {} // PHPUnit 11 style — PHP 8 native attributes (preferred) use PHPUnit\Framework\Attributes\DataProvider; use PHPUnit\Framework\Attributes\Group; #[DataProvider('valuesProvider')] #[Group('integration')] public function testProcess($input, $expected): void {} ``` **Common attribute mapping:** Old annotationPHPUnit 11 attribute`@dataProvider foo``#[DataProvider('foo')]``@depends testBar``#[Depends('testBar')]``@group name``#[Group('name')]``@covers Foo::bar``#[CoversMethod(Foo::class, 'bar')]``@uses Foo``#[UsesClass(Foo::class)]``@before``#[Before]``@after``#[After]``@requires PHP 8.1``#[RequiresPhp('8.1')]``@expectedExceptionMessage …``$this->expectExceptionMessage(…)` in body### Writing Tests for 7x Prime Bundles [](#writing-tests-for-7x-prime-bundles) Place test classes in `src/YourBundle/Tests/` following PHPUnit conventions. Use `PHPUnit\Framework\TestCase` for unit tests and `Symfony\Bundle\FrameworkBundle\Test\WebTestCase` for full HTTP functional tests: ```
