The Memcached Driver

Introduction

The Memcached driver provides a simple and efficient way to store and retrieve data in-memory using multiple Memcached pools.

It is based on the excellent Symfony Cache component and provides a convenient interface for interacting with Memcached servers.

Installation

Install the driver via composer by running:

composer require kipchak/driver-memcached

Initialise the Driver

Add the following line to your drivers/drivers.php file:

\Mamluk\Kipchak\Driver\Memcached\Memcached::iniitalise($container);

Configuration

The configuration in kipchak.memcached.php can be used to configure muliple Memached pools:

return [
    'enabled' => true,
    'pools' => [
        'cache' => [
            ['host' => 'memcached', 'port' => 11211]
        ],
        'sessions' => [
            ['host' => 'memcached', 'port' => 11211]
        ]
    ],
];

Please see the configuration file in the starter project at https://1x.ax/mamluk/kipchak/starter/~files/master/config/kipchak.memcached.php for full configuration details.

Usage

use Kipchak\Driver\Memcached\Memcached;
use Symfony\Contracts\Cache\ItemInterface;

// Get a specific pool
$cache = Memcached::get('cache');
$sessions = Memcached::get('sessions');

$value = $cache->get('my_cache_key', function (ItemInterface $item) {
    $item->expiresAfter(3600);
    return 'expensive computation result';
});

// Delete from cache
$cache->delete('my_cache_key');
