*eufony/cache provides the most trivial implementations of PSR-6 and PSR-16 as well as other essentials for getting started with caching.*

*eufony/cache* is a small PHP library that handles basic caching needs without overcomplicating things. It implements the simplest kinds cache pools, supporting both the [PSR-6](https://www.php-fig.org/psr/psr-6/)and [PSR-16](https://www.php-fig.org/psr/psr-16/) standards, plus:

- Adapter classes to convert between PSR-6 and PSR-16 caching implementations.
- Utility classes to aid in the implementation of other caching backends.
- An extension to the caching standards using a tag-based cache invalidation technique.
- A framework to hook in to and modify the cache values on their way in and out of the pool.

Interested? [Here's how to get started.](#getting-started)

Getting started
---------------

[](#getting-started)

### Installation

[](#installation)

*eufony/cache* is released as a [Packagist](https://packagist.org/) package and can be easily installed via [Composer](https://getcomposer.org/) with:

```
composer require "eufony/cache"

```

### Basic Usage

[](#basic-usage)

*For a more detailed documentation, see [here](docs).*

*eufony/cache* provides three different caching implementations:

```
// An in-memory cache pool using a PHP array.
$cache = new ArrayCache();

// An in-memory cache pool using the `apcu` extension,
// which can share cache values between processes on the same host.
$cache = new ApcuCache();

// A fake cache based on the Null Object Pattern.
$cache = new NullCache();
```

You can extend these cache pools using [marshallers](https://github.com/eufony/marshaller) and a tag-based cache invalidation interface.

It also provides adapter classes to convert between PSR-6 and PSR-16 cache implementations:

```
// Convert from PSR-6 to PSR-16.
$cache = new Psr16Adapter(/* ... */);

// Convert from PSR-16 to PSR-6.
$cache = new Psr6Adapter(/* ... */);
```
