README

Limcache is a small non-persistent cache manager that supports LRU and MRU replacement algorithms. Also it has optional Judy support.

Requirements

• PHP >= 5.4
• Judy (optional)

Installation

You can install Limcache via Composer:

composer require herroffizier/limcache:dev-master

Usage

At first, choose replacement algorithm:

// Use LRU:
$strategy = new \Limcache\strategy\LRU(100); // 100 is max item count in cache

// Or MRU:
$strategy = new \Limcache\strategy\MRU(100);

After that you can create cache:

$cache = new \Limcache\Cache($strategy);

Since \Limcache\Cache implements \ArrayAccess and \Countable interfaces you can use it as array in most cases:

// Save item in cache:
$cache['key1'] = 'somedata';

// Get item value:
$cache['key1'];

// Try to get non-existent item:
$cache['key2']; // will return null

// Do some ordinary things:
count($cache);
isset($cache['key1']);
unset($cache['key1']);

In addition cache object has few useful methods which may help to determine cache efficiency:

// Get cache hits:
$cache->getHits();

// Get cache misses:
$cache->getMisses();
