react-thread-pool

This is a multiprocessing library for PHP based on pcntl_fork().

Status: alpha
Tests: none

Features

• Running Parallel Processes out of a single Process
• Give the entire environment to the Thread without thinking on serialisation
• Control the thread (Start, Stop, Kill) + Custom messages
• Running tons of threads on an single ThreadPool (be careful with your processor)
• Setting up threads to observe external resources

Requirements

• Linux/Unix platform
• PHP >= 5.4 (also PHP 7)
• custom functions (pcntl_fork, pcntl_waitpid, posix_getpid)
• reactphp/event-loop
• igorw/evenement
• [optional] PHP Extension libevent (pect/libevent-0.1.0)
• [optional] PHP Extension Event http://php.net/manual/en/book.event.php

Basic Usage

Create an EventLoop:

$loop = ForkableFactory::create();

*The loop is the same as reactphp/event-loop so you can also use this for your server
Creating a default thread to perform heavy work outside your parent process:

use RogerWaters\ReactThreads\EventLoop\ForkableLoopInterface;
use RogerWaters\ReactThreads\ThreadBase;

class ExampleThread extends ThreadBase
{
    protected function InitializeExternal(ForkableLoopInterface $loop)
    {
        //Do your external logic here
        //you can also use $loop functions
        //Use $this->kill(); to complete execution from child
        $this->kill();
    }
}

All together: ```php //create thread $thread = new ExampleThread($loop); //start thread and do external logic $thread->start();

//wait for the thread to complete $thread->on('stopped',function() use ($loop) { //thread is done //stop the parent process $loop->stop(); });

//you can do any other operations here without affecting the thread

//run the loop to wait for completion $loop->run();

For communicable threads see example_3.php and example_4.php
