Memcached

Memcached is a cache package using Memcached as backend. Therefor Memcached is required to be install for this package to work. However, Phapi has one golden rule regarding cache backends:

A working cache should not be a requirement for the application to work. So if Phapi is unable to connect to the cache backend it wont stop the execution. Instead the configured cache will be replaced with a dummy cache, new NullCache().

Memcache vs Memcached

Please note that there are two cache provider packages available: phapi/cache-memcache and phapi/cache-memcached. The difference between the packages is the PHP extension they use.

So which one should you use?

It depends on two things:

Which extension do you have installed?
PHP version. Both the Memcache extension and the Memcached exists for PHP 5.6 and HHVM. But according to the gophp7 project extension catalog only Memcached will be updated to PHP 7.

Installation

The package is not installed by default by the Phapi framework. Add the package as a dependency in composer to install the package.

$ composer require phapi/cache-memcached:1.*

Configuration

Configure the package and add it to the container to enable it.

<?php
$container['cache'] = function ($container) {
    return new \Phapi\Cache\Memcached($servers = [
        [
            'host' => 'localhost',
            'port' => 11211
        ],
    ]);
};

Add as many memcache servers as you want by extending the array.

See the configuration documentation for more information about how to configure the integration with the Phapi Framework.
