Container Laravel Package

Technical Evaluation

The package is a PHP-FIG standard (PSR-11) defining container interfaces, not an implementation. Laravel's built-in container already implements this interface, making it a natural fit. Integration feasibility is high since Laravel already depends on this package (e.g., psr/container:^2.0 in Laravel 9+). Technical risk is minimal due to its stability as a standard, but PHP 7.4+ requirement must align with project constraints (Laravel 9+ requires PHP 8.0+). Key questions:

• Does the project need custom PSR-11 implementations (unlikely for Laravel, as it provides its own)?
• Are third-party libraries relying on PSR-11 compatibility properly validated against Laravel's implementation?
• How will version conflicts be handled if multiple container implementations coexist (e.g., in polyglot projects)?

Integration Approach

Stack fit is seamless: Laravel’s Illuminate\Container\Container natively implements Psr\Container\ContainerInterface, so no additional configuration is needed. Migration path is trivial for existing Laravel projects (already included via composer dependencies). Compatibility is guaranteed for Laravel 8+ (PSR-11 v1) and 9+ (PSR-11 v2), with PHP version requirements aligned (PHP 8.0+ for Laravel 9+). Sequencing is handled automatically by Composer during installation; no manual steps required. For non-Laravel projects, adoption would require wiring a PSR-11-compliant container (e.g., Symfony DI) but this is irrelevant for pure Laravel contexts.

Operational Impact

Maintenance burden is near-zero as the package is stable and rarely updated (last release 2021). Support is robust via PHP-FIG’s governance and Laravel’s ecosystem (e.g.,
