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

Install the library with composer:

``` bash
composer require symfony-bundles/fork
```

How to use (only cli-mode)
--------------------------

Create the fork service:

``` php
use SymfonyBundles\Fork;

$fork = new Fork\Fork();
```

Create a task that implements an interface `SymfonyBundles\Fork\TaskInterface`.
For example:

``` php
namespace AppBundle\Task;

use SymfonyBundles\Fork\TaskInterface;

class DemoTask implements TaskInterface
{
    public function execute()
    {
        echo "Hello World!\n";
    }
}
```

Now that the task is created, you can execute her in a plurality processes:

``` php
use AppBundle\Task\DemoTask;

$task = new DemoTask();

$fork->attach($task)->run(4)->wait(); // 4 - this is number of subprocesses
```

And another example:
``` php
$task1 = new DemoTask();
$task2 = new DemoTask();
$task3 = new DemoTask();

$fork->attach($task1)->attach($task2)->attach($task3);
$fork->run(); // by default, the optimal number of subprocesses will be determined
$fork->wait();
```

If you call method `wait`, the current process (main) will wait while all child processes will be finished.
