Array PSR-6 cache pool

This package provides in-memory PSR-6 and PSR-16 cache implementations. The pool supports tags and hierarchical keys.

Values live only for the current PHP process. This adapter works well in tests and short-lived scripts.

Installation

composer require cache/array-adapter:^3.0

Usage

use Cache\Adapter\PHPArray\ArrayCachePool;

$pool = new ArrayCachePool();

Limit stored items

Pass a positive maximum item count as the first constructor argument. The default null value keeps every item for the process lifetime.

$pool = new ArrayCachePool(1_000);

When the pool reaches the limit, saving a new key removes the key in the next storage slot. Updating an existing key keeps its slot.

Upgrading to version 3

Version 3 stores a generation snapshot with each tagged item and a separate marker for each tag. Array caches are process-local, so new workers start with an empty cache.
