Install

composer require fivesqrd/mutex:1.0.*

<?php
require_once realpath(__DIR__ . '/../vendor/autoload.php');

use Fivesqrd\Mutex;

$mutex = new Mutex\Factory([
    'aws' => array(
        'version'  => '2012-08-10',
        'region'   => 'eu-west-1',
        'endpoint' => 'http://192.168.254.10:8000',
        'credentials' => array(
            'key'    => 'my-key',
            'secret' => 'my-secret',
        )
    ),
    'namespace' => 'My-Example-App',
    'table'     => 'My-DynamoDb-Table' 
]);

echo date('Y-m-d H:i:s') . " Starting job\n";

if (!$mutex->lock(basename($argv[0]))->acquire(10)) {
    echo "- The work slot for this job has been locked, skipping...\n";
    exit;
}

echo  "- Lock acquired successfully...\n";
