This module is only for integrating third-party packages that rely on the PSR interface provisions.** Quick Start ----------- [](#quick-start) 1. Install with Composer: `> composer require codeigniter4/cache` 2. Integrate with your favorite packages: ``` use CodeIgniter\Psr\Cache\SimpleCache; use Kreait\Firebase\Factory; ... $factory = (new Factory)->withVerifierCache(new SimpleCache()); ``` Features -------- [](#features) A set of adapters fully-compliant with PSR-6 and PSR-16 to integrate with CodeIgniter 4's Caching Driver. Installation ------------ [](#installation) Install easily via Composer to take advantage of CodeIgniter 4's autoloading capabilities and always be up-to-date: - `> composer require codeigniter4/cache` Or, install manually by downloading the source files and adding the directory to `app/Config/Autoload.php`. Usage ----- [](#usage) This module has adapters for CodeIgniter 4 to supply the following FIG PHP Standards Recommendations (PSR): - [Caching Interface](https://www.php-fig.org/psr/psr-6) - [Simple Cache](https://www.php-fig.org/psr/psr-16) If you just need a caching agent then you should use the framework's native [Caching Driver](https://codeigniter4.github.io/CodeIgniter4/libraries/caching.html). These adapters are intended to integrate with any library or project that requires either of the following: - [psr/cache-implementation](https://packagist.org/packages/psr/cache/dependents?order_by=downloads) - [psr/simple-cache-implementation](https://packagist.org/packages/psr/simple-cache/dependents?order_by=downloads) The interfaces are provided by the following classes: - `Psr\Cache\CacheItemInterface` provided by `CodeIgniter\Psr\Cache\Item` - `Psr\Cache\CacheItemPoolInterface` provided by `CodeIgniter\Psr\Cache\Pool` - `Psr\SimpleCache\CacheInterface` provided by `CodeIgniter\Psr\Cache\SimpleCache` By default the adapters (`Pool` and `SimpleCache`) will work with the Caching Driver as defined in you cache configuration (e.g. **app/Config/Cache.php**). You may create either driver explicitly with an alternative Cache Handler or Config: ``` $sharedCacheServicePool = new \CodeIgniter\Psr\Cache\Pool(); $fileHandler = new \CodeIgniter\Cache\Handlers\FileHandler(config('Cache')); $explicitFileHandlerSimpleCache = new \CodeIgniter\Psr\Cache\SimpleCache($fileHandler); $config = config('Cache'); $config->prefix = 'banana-'; $alternativeConfigPool = new \CodeIgniter\Psr\Cache\Pool($config); ``` Testing ------- [](#testing) Testing of the underlying Caching Driver is handled in the [CodeIgniter 4 repo](https://github.com/codeigniter4/CodeIgniter4/tree/develop/tests/system/Cache). These adapters are tested with the [PHP Cache Integration Tests](https://github.com/php-cache/integration-tests), by Aaron Scherer. You may run the test suite by cloning this repo, installing all dependencies, and running: - `> composer test` ### Health Score 38 — LowBetter than 85% of packages Maintenance30 Infrequent updates — may be unmaintained Popularity35 Limited adoption so far Community17 Small or concentrated contributor base Maturity57 Maturing project, gaining track record Bus Factor2 2 contributors hold 50%+ of commits How is this calculated?**Maintenance (25%)** — Last commit recency, latest release date, and issue-to-star ratio.
