Creating a new server instance

<?php

ini_set('log_errors', 1);
ini_set('error_log', '/var/log/php-cache.log');
require_once 'vendor/autoload.php';

use PhpCache\CacheServer\CacheServer;
use PhpCache\ServiceManager\ConfigAggregator;
use PhpCache\ServiceManager\ServiceManager;
// You can import multiple config files to overwrite parameters in the basic config or add extra parameters, including dependency injection
$config = include_once 'config.php';
$configAggregator = new ConfigAggregator();
$configAggregator->addConfig($config);
$serviceManager = new ServiceManager($configAggregator->getMergedConfig());
$server = $serviceManager->get(CacheServer::class);
$server->run();

Running the server:

php testServer.php

OR

mv daemon.sh /etc/init.d/php-cache
chmod +x /etc/init.d/php-cache
# now you can use systemctl style service management
sudo service php-cache start

Note: you can modify the contents of daemon.sh if you want to use other directories

Configuration array:

• config: Basic configuration array
  -- memoryLimit: as the name suggests, after we exceed the limit, our data in the cache pool gets backed up to file system
  -- location: server IP address or socket file location (string)
  -- port: the port to run the sockets on (number)
  -- bufferSize: how big chunks of data is being read from a stream (bytes)
  -- ttl: time to live; how long an entry should take space up in the cache pool before being deleted (seconds)
  -- backupTime: schedule backups (seconds)
  -- backupDir: where to store backed up data? A backup is made when we are shutting down the server service, when the scheduled backup occures or our cache pool exceeded it's memory limit
  -- socketType: which socket type should we use? Open a port on the network for the socket or create a file for the socket. Values must be either file (CacheIOHandler::SOCKET_TYPE_FILE) or ip (CacheIOHandler::SOCKET_TYPE_IP)
• services: service manager configuration
  -- aliases: a name assigned for a real service (Example: 'cache-server' => CacheServer::class)
  -- factories: service name with factory name for service pairs
  -- invokables: services with no dependencies

Creating a new client instance

<?php
include_once('vendor/autoload.php');

use PhpCache\CacheClient\CacheClient;
use PhpCache\ServiceManager\ServiceManager;

$config = require_once 'config.php';
$serviceManager = new ServiceManager($config);
/* @var $client CacheClient */
$client = $serviceManager->get(CacheClient::class);
$client->set('test', 'ASD');
echo $client->get('test');

You can run the client either from browser or console

php testClient.php

CLI Commands:

./phpCache get <key> gets entries for the specified key. If no key is specified, it returns all entries.
./phpCache set <key> <value> pushes an entry to the cache pool with the given key - value pair.
./phpCache delete <key> deletes the entry with the given key
