Splits large SQL 'WHERE column IN (...)' clauses into batches to avoid database performance issues. The class is self-contained, taking a connection and a list of values, and returns a batched query. It demonstrates a reusable optimization pattern for any application dealing with large IN lists.

A decorator that adds an in-memory (local) caching layer on top of any ICache implementation. It caches get() results in a simple array and clears on set/remove. This is a generic, isolated pattern for adding a warm cache to any caching backend without modifying the underlying implementation.

Implements Twitter-style Snowflake ID generation for distributed systems, producing unique, time-sortable 64-bit IDs. It uses a sequence (from database or other source) to ensure uniqueness within a timestamp. This is a self-contained, reusable component for generating IDs in distributed applications.

Abstract base class for rate limiting that implements the template method pattern. Subclasses like UserRateLimit and AnonRateLimit define the key and throttling logic. The class provides reusable infrastructure for rate limiting across controllers, easily extractable for any PHP application needing API rate limiting.

Implements a share recipient type for email addresses, extending an abstract collaborator search pattern. It validates email formats, builds recipients, and returns an interaction receiver. This demonstrates a clean implementation of a pluggable share type, reusable as a template for adding new share recipient types (e.g., phone, social) in any sharing system.
