symfony/polyfill-apcu
Symfony Polyfill for APCu: provides compatible APCu functions/constants for PHP environments where the extension is missing or incomplete. Helps libraries rely on APCu-style caching across versions and platforms with a lightweight fallback implementation.
Architecture fit: The package provides a pure-PHP fallback for APCu functions, enabling compatibility with PHP versions lacking the APCu extension. It fits well in projects requiring cross-version support but introduces abstraction overhead for caching logic. Best suited for environments where APCu extension installation is inconsistent (e.g., shared hosting, legacy systems) but not ideal for performance-critical paths where native extension speed is required.
Integration feasibility: High. Composer-based installation requires zero code changes to existing apcu_* calls.
