SymfonyBundles Fork Library

, _(*1)

![Build Status][testing-image] [][scrutinizer-code-quality-link] [][code-coverage-link] , _(*2)

Installation

Install the library with composer:, _(*3)

``` bash composer require symfony-bundles/fork, <sub>(*4)</sub>

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:, <sub>(*5)</sub>

``` php namespace AppBundle\Task;, <sub>(*6)</sub>

use SymfonyBundles\Fork\TaskInterface;, <sub>(*7)</sub>

class DemoTask implements TaskInterface { public function execute() { echo "Hello World!\n"; } }, <sub>(*8)</sub>

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();, <sub>(*9)</sub>

$fork->attach($task1)->attach($task2)->attach($task3); $fork->run(); // by default, the optimal number of subprocesses will be determined $fork->wait(); ```, <sub>(*10)</sub>

If you call method wait, the current process (main) will wait while all child processes will be finished., <sub>(*11)</sub>
