Product Decisions This Supports

Ensures consistent internationalization features (date/number formatting, collation) across environments where PHP Intl extension is unavailable, eliminating deployment blockers for global applications
Reduces build vs buy tradeoffs by providing a production-ready fallback instead of custom polyfill development, accelerating feature delivery for i18n requirements
Supports roadmap goals for multi-region deployments by abstracting server configuration dependencies, allowing teams to focus on application logic rather than environment-specific quirks

When to Consider This Package

✅ When targeting shared hosting or legacy systems where Intl extension isn't enabled by default
✅ When needing basic English locale support for date/number formatting without server configuration changes
❌ When requiring non-English locales (polyfill only supports "en")
❌ When the project already mandates Intl extension installation (e.g., via Docker or managed platforms)
❌ For advanced ICU features beyond the polyfill's scope (e.g., complex locale-specific rules)

Executives: "This MIT-licensed package guarantees our application's internationalization features work flawlessly in any hosting environment—no server tweaks required. It's battle-tested by Symfony's ecosystem, eliminating deployment risks and enabling global scalability with zero added cost."
Engineering: "A lightweight, dependency-free polyfill that provides drop-in compatibility for Intl functions in environments without the extension. It's been rigorously tested in production, reduces maintenance overhead for locale-related features, and integrates seamlessly with existing PHP stacks."
