Polyfill Php80 Laravel Package

Technical Evaluation

Architecture fit: The package is framework-agnostic and integrates seamlessly into Laravel's Composer-based architecture. It provides transparent backports for specific PHP 8.0 features without requiring code rewrites or architectural changes, making it ideal for projects maintaining compatibility with older PHP versions while leveraging modern syntax.

Integration feasibility: High. As a pure Composer dependency, it requires only composer require symfony/polyfill-php80 with no configuration. Laravel's native Composer usage ensures trivial installation, and the package's minimal dependencies (PHP ≥7.2) align with Laravel 8+ requirements.

Technical risk: Very low. Symfony maintains rigorous testing and versioning, with no known security vulnerabilities. The polyfill only activates when native PHP features are absent, avoiding runtime conflicts. However, edge cases may arise if custom implementations of polyfilled functions exist in legacy code.

Key questions:

• What specific PHP 8.0 features does the project currently use that are unavailable in the target PHP version?
• Is the project's current PHP version ≥7.2 (required by the polyfill)?
• Are there existing custom implementations of polyfilled functions (e.g., str_contains) that could conflict with the polyfill?
• Does the team plan to upgrade PHP to 8.0+ in the near term, reducing long-term need for the polyfill?

Integration Approach

Stack fit: Perfect alignment with Laravel's ecosystem. The
