This library has been designed with the intention of preventing the execution of multiple instances of a script.

In the event that it is intended for use in batch processing and a script is already running, all subsequent attempts at execution can be terminated until the current process completes.

Installation
------------

[](#installation)

```
composer require sunaoka/process-guard-php
```

Basic Usage
-----------

[](#basic-usage)

```
use Sunaoka\ProcessGuard\Drivers\FileDriver;
use Sunaoka\ProcessGuard\LockFactory;

$driver = new FileDriver();
$factory = new LockFactory($driver);

$lock = $factory->create('Preventing Multiple Instances', ttl: 60.0);
if ($lock->acquire() === false) {
    // already running
    exit;
}

// You can do some processing

$lock->release();
```
