Doctrine Dateinterval Laravel Package

Product Decisions This Supports

• Time-based scheduling systems: Enable storage and querying of recurring events (e.g., subscriptions, billing cycles, or maintenance schedules) with precise interval logic (e.g., "P1Y2M" for yearly + 2 months).
• Date arithmetic in queries: Replace manual PHP calculations (e.g., start_date + interval) with declarative DQL functions like DATE_INTERVAL('P1Y'), improving query readability and maintainability.
• Legacy system modernization: Migrate from custom interval storage (e.g., strings or integers) to a typed, queryable DateInterval field in Doctrine entities.
• Roadmap prioritization: Justify investment in Doctrine-based systems by reducing technical debt for date/time handling (e.g., avoid reinventing interval storage/parsing).
• Build vs. buy: Opt for this package over custom solutions if the team lacks time/resources to build robust interval type handling for Doctrine.

When to Consider This Package

• Use this if:
  • Your application heavily relies on Doctrine DBAL/ORM for data persistence.
  • You need to store/retrieve recurring intervals (e.g., subscriptions, cron jobs) with native type safety.
  • Your queries involve date arithmetic (e.g., filtering records based on time durations like "events lasting < 1 year").
  • You’re using Symfony or a custom Doctrine setup and want minimal configuration overhead.
• Look elsewhere if:
  • You’re not using Doctrine: This package is DBAL/ORM-specific; alternatives like native PHP DateInterval or a NoSQL database may suffice.
  • Your intervals are static or simple: Hardcoded values or integer-based storage (e.g., "seconds since epoch") might be overkill.
  • You need active maintenance: The package is archived (last updated in 2016); evaluate risks for long-term projects.
  • Your team prefers modern PHP: Requires PHP ≥5.3.3 and Doctrine ≤2.x; newer projects may use Doctrine 3+ or alternative tools like DateTimeImmutable.

How to Pitch It (Stakeholders)

For Executives: "This package lets us store and query time intervals (e.g., 'every 6 months') directly in our database using Doctrine, reducing bugs from manual date calculations. For example, we could filter subscriptions expiring in <1 year with a simple query like WHERE expiry_date > DATE_INTERVAL('P1Y'). It’s a lightweight, MIT-licensed solution that integrates seamlessly with our existing Doctrine setup, saving dev time and improving data integrity for time-sensitive features like billing or scheduling."

For Engineers: *"This adds a dateinterval Doctrine type and a DATE_INTERVAL DQL function, enabling native storage/querying of DateInterval objects. Key benefits:

• Type safety: Store intervals as proper objects (e.g., P1Y2M) instead of strings/integers.
• Query flexibility: Use DQL for interval comparisons (e.g., WHERE duration < DATE_INTERVAL('P2Y')).
• Symfony-friendly: Minimal config via YAML or PHP. Tradeoff: Archived but stable; ensure compatibility with your Doctrine version (2.x)."*
