Yii Cache Library - APCu Handler


Latest Stable Version Total Downloads Build status Scrutinizer Code Quality Code Coverage Mutation testing badge static analysis type-coverage

This package uses the PHP APC extension and implements PSR-16 cache.

This option can be considered as the fastest one when dealing with a cache for a centralized thick application (e.g. one server, no dedicated load balancers, etc.).

Installation

The package could be installed with composer:

composer require yiisoft/cache-apcu

General usage

The package does not contain any additional functionality for interacting with the cache, except those defined in the PSR-16 interface.

$cache = new \Yiisoft\Cache\Apcu\ApcuCache();
$parameters = ['user_id' => 42];
$key = 'demo';

// try retrieving $data from cache
$data = $cache->get($key);

if ($data === null) {
    // $data is not found in cache, calculate it from scratch
    $data = calculateData($parameters);
    
    // store $data in cache for an hour so that it can be retrieved next time
    $cache->set($key, $data, 3600);
}

// $data is available here

In order to delete value you can use:

$cache->delete($key);
// Or all cache
$cache->clear();

To work with values in a more efficient manner, batch operations should be used:

  • getMultiple()
  • setMultiple()
  • deleteMultiple()

This package can be used as a cache handler for the Yii Caching Library.
