README

Please use phoole/cache instead.

phossa2/cache is a PSR-6 compliant caching library for PHP. It supports various drivers and useful features like bypass, encrypt, stampede protection etc.

It requires PHP 5.4, supports PHP 7.0+ and HHVM. It is compliant with PSR-1, PSR-2, PSR-3, PSR-4, PSR-6 and the proposed PSR-5.

Installation

Install via the composer utility.

composer require "phossa2/cache"

or add the following lines to your composer.json

{
    "require": {
       "phossa2/cache": "2.*"
    }
}

Features

• Fully PSR-6 compliant.

• Support all serializable PHP datatypes.

• Extensions included:

  • Bypass: If sees a trigger in URL (e.g. '?nocache=true'), bypass the cache.

  • Stampede Protection: Whenever cached object's lifetime is less than a configurable time, by a configurable percentage, the cache will return false on 'isHit()' which will trigger re-generation of the object.

  • Encrypt: A simple extension to encrypt the serialized content.

  • DistributedExpiration: Even out the spikes of item misses by alter expiration time a little bit.

• Drivers

  • StorageDriver

    The storage driver uses phossa2/storage local or cloud storage.

  • NullDriver

    The blackhole driver, can be used as fallback driver for all other drivers.

Usage

• Simple usage

  /*
   * cache dir default to local sys_get_temp_dir() . '/cache'
   */
  $cache = new CachePool();
  
  $item = $cache->getItem('/data.cache');
  if (!$item->isHit()) {
      $value = calcuate_data();
      $item->set($value);
      $cache->save($item);
  }
  $data = $item->get();

• Specify the driver

  use Phossa2\Cache\Driver\StorageDriver;
  use Phossa2\Storage\Storage;
  use Phossa2\Storage\Filesystem;
  use Phossa2\Storage\Driver\LocalDriver;
  
  $driver = new StorageDriver(
      new Storage('/', new Filesystem(new LocalDriver(sys_get_temp_dir()))),
      '/cache'
  );
  
  $cache = new CachePool($driver);

• Use extensions

  /*
   * DistributedExpiration extension
   */
  use Phossa2\Cache\CachePool;
  use Phossa2\Cache\Extension\DistributedExpiration;
  
  $cache = new CachePool();
  $cache->addExtension(new DistributedExpiration());
