**IDCT Rapid Cache Client** is a high-performance Redis-backed caching library for PHP. At its core it is a clean [PSR-16 (SimpleCache)](https://www.php-fig.org/psr/psr-16/)implementation, so it drops straight into any framework or library that speaks the standard cache contract. On top of that baseline it adds the features real applications keep reaching for but PSR-16 leaves out: **tag-based grouping and invalidation, FIFO queues, sets, sorted sets, and atomic counters** - all exposed through the `CacheServiceInterface` contract.

The package ships **two clients** that share the same PSR-16 + tagging surface but differ in how values land in Redis:

- **`RapidCacheClient`** — the general-purpose client. Stores any serializable PHP value (objects, nested arrays, `DateTime`, …) as a single Redis STRING using the compact binary `ext-igbinary` serializer. Adds queues, sets, sorted sets, and whole-value counters on top.
- **`HashRapidCacheClient`** — purpose-built for flat associative arrays of scalars. Each value is stored as a native Redis HASH so individual fields can be read, written, or atomically incremented without round-tripping the whole record (`HGET`/`HSET`/`HINCRBY`). No serializer — the wire format is plain Redis hash fields.

Speed comes from two deliberate choices: both clients talk to Redis (or any Redis-compatible server such as [Valkey](https://valkey.io/)) through the native `ext-redis` C extension, and the string client serializes values with `ext-igbinary` so arbitrary PHP values round-trip losslessly and cheaply. Bulk operations are pipelined and chunked, connections are established lazily and re-established transparently, and every Redis-level error is translated into a PSR-16 exception so your calling code stays backend-agnostic.
