README

Winter Thread provides a clean, object-oriented API for running and controlling background processes in PHP, simulating a traditional threading model for parallel and long-running tasks.

It abstracts away the complexities of proc_open and posix signals into a powerful and easy-to-use interface.

Key Features

• 🚀 Fluent, Object-Oriented API: Manage background processes as objects.
• ⏯️ Full Process Control: start(), join(), pause(), resume(), terminate(), and kill().
• 🏷️ Advanced Process Naming: Identify your processes easily with namespaces, names, and tags.
• 🔒 Secure by Default: Optional signed serialization for closures via opis/closure.
• 🧩 Extensible: Easily override the runner script for deep framework integration.
• ☕ Java-like API: Familiar method names like isAlive() and join() for an easy learning curve.

Requirements

• PHP >= 8.1
• ext-pcntl
• ext-posix
• (Optional) opis/closure for serializing closures.

Installation

composer require flytachi/winter-thread

Quick Start

Here's how easy it is to run a long-running task in the background without blocking your main script.

<?php

require 'vendor/autoload.php';

use Flytachi\Winter\Thread\Runnable;
use Flytachi\Winter\Thread\Thread;

// 1. Define your task by implementing the Runnable interface.
//    The logic inside run() will be executed in a separate process.
class VideoProcessingTask implements Runnable {
    private string $videoFile;

    public function __construct(string $videoFile) {
        $this->videoFile = $videoFile;
    }

    public function run(): void {
        echo "Child Process (PID: " . getmypid() . "): Starting processing for {$this->videoFile}...\n";
        sleep(10); // Simulate a long-running encoding job
        echo "Child Process (PID: " . getmypid() . "): Finished processing {$this->videoFile}.\n";
    }
}

echo "Main Script (PID: " . getmypid() . "): Starting application.\n";

// 2. Create a new Thread instance with your task.
//    You can also provide metadata for process identification.
$thread = new Thread(
    new VideoProcessingTask('movie.mp4'),
    'ETL',          // Namespace
    'ProcessVideo', // Name
    'job-42'        // Tag
);

// 3. Start the thread. This immediately returns the child process PID.
$pid = $thread->start();

echo "Main Script: Video processing started in background (PID: $pid).\n";

// The main script can continue doing other work here...
echo "Main Script: Doing other work while video is processing...\n";
sleep(2);

// 4. (Optional) Wait for the thread to finish and get its exit code.
//    This will block the main script until the child process completes.
echo "Main Script: Waiting for the task to complete...\n";
$exitCode = $thread->join();
echo "Main Script: Task completed with exit code: $exitCode.\n";
