Symfony Playground Laravel Package
krak/symfony-playground
A Symfony playground for experimenting with framework features, components, and configuration in a safe sandbox. Use it to prototype ideas, test integrations, and explore Symfony behavior before applying patterns to real projects.
Symfony Dev Playground for Testing Code
Frequently asked questions about Symfony Playground
- Is krak/symfony-playground a Laravel package?
- No. It is a Symfony-based development playground with no Laravel service provider, facade, config publishing, or other Laravel integration surface. It is designed as a standalone scaffold for experimenting with Symfony components, not as a Composer dependency for a Laravel application.
- Can I install krak/symfony-playground with Composer in a Laravel project?
- You should not. There is no meaningful Composer value chain into a Laravel app; the realistic use is cloning the repository and running it as a separate standalone project. Adding it to a Laravel dependency graph risks Composer conflicts because it targets older Symfony and PHP versions. Keep it out of your Laravel composer.json.
- Does krak/symfony-playground support Laravel 10 or Laravel 11?
- No. The package has no Laravel version support because it is not a Laravel package. Its last release was in June 2020 and it likely targets PHP 7.x/8.0 and Symfony 4/5, which conflicts with modern Laravel requirements of PHP 8.2+ and current Symfony components. Assume incompatibility by default with Laravel 10 or 11.
- What PHP and Symfony versions does krak/symfony-playground require?
- The project is a 2020-era Symfony scaffold, so it most likely targets PHP 7.x through early 8.0 and Symfony 4 or 5. Those versions are likely past end-of-life and are not verified for PHP 8.2 or 8.3. Check the original composer.json in the repository before running anything, and treat outdated transitive dependencies as a security risk.
- Can I use krak/symfony-playground to test Laravel code?
- Not directly. It boots a Symfony kernel and container, not Laravel's application container, so Laravel-specific features such as Eloquent, service providers, facades, and artisan commands will not behave as they do in a real app. For Laravel code, use php artisan tinker, a Pest or PHPUnit scratch test, or a disposable Laravel Sail project instead.
- Is krak/symfony-playground maintained and safe for production?
- No. It has zero stars, zero dependents, no meaningful community validation, and its last release was June 2020. That means no security patching, no PHP 8.2/8.3 verification, and pinned Symfony versions that are likely end-of-life. Treat any execution as untrusted code in an isolated environment, never in production or on a machine with credentials.
- What are safer alternatives to krak/symfony-playground for Laravel developers?
- Use Laravel-native scratch tools: php artisan tinker for quick REPL experiments, a Pest or PHPUnit test for reproducible snippets, or a disposable Laravel Sail container for isolated app-like testing. If you specifically need a Symfony sandbox, create a fresh Symfony project with a currently supported version rather than cloning an unmaintained 2020 scaffold. These options avoid dual-framework drift and keep dependencies current.
- How do I run krak/symfony-playground safely if I still want to experiment?
- Clone it into a disposable directory and run it inside a container with no host network access and no credentials mounted. Lock Composer to the existing manifest, do not add new dependencies, and assume the dependency tree contains known vulnerabilities. Use it only to answer narrow questions, then discard the environment and reimplement any useful findings as Laravel-native code or tests.
- Can I reuse Symfony components from krak/symfony-playground inside Laravel?
- You can reimplement ideas manually, but you should never vendor the playground into a Laravel app. Laravel already pulls in Symfony components transitively, and mixing the playground's older pinned versions can create Composer resolution conflicts and dual-container ambiguity. If a component proves useful, add the maintained Symfony package directly to Laravel and write a Laravel-native integration test.
- Why would a Laravel team use a Symfony playground at all?
- Only if the organization also maintains Symfony services and needs a shared scratchpad for Symfony-specific behavior such as bundles, YAML config, or kernel bootstrapping. A Laravel-first team gains no transferable advantage because the mental model diverges from Eloquent, service providers, and Laravel's container. For pure Laravel work, a Laravel scratch app or test is simpler and safer.
