Installation
------------

[](#installation)

The recommended method of installing this library is via [Composer](//getcomposer.org/).

Run the following command from your project root:

```
$ composer require duncan3dc/cache
```

Quick Examples
--------------

[](#quick-examples)

There are 2 cache providers available, one is the local filesystem and the other is simple array cache in memory.

Using the `FilesystemPool` will persist data forever (or until the filesystem is purged).

```
$cache = new \duncan3dc\Cache\FilesystemPool(sys_get_temp_dir());

# The $cache object implements PSR-6
$userData = $cache->getItem("user_data")->get();

# ...and PSR-16
$userData = $cache->get("user_data");
```

Using the `ArrayPool` will not persist data beyond the current request.

```
$cache = new \duncan3dc\Cache\ArrayPool();

# The $cache object implements PSR-6
$userData = $cache->getItem("user_data")->get();

# ...and PSR-16
$userData = $cache->get("user_data");
```

There's also a trait to allow any method to be automatically cached.

```
$cache = new class {
    use \duncan3dc\Cache\CacheCallsTrait;

    public function _getData()
    {
        return [];
    }
};

$cache->getData();
```

The first time `getData()` is called then `_getData()` will be run, but after that future calls to `getData()` will just return the cached result from the first call to `_getData()`.
