WordPress with TrueAsync PHP

Test build demonstrating WordPress running on TrueAsync PHP with NGINX Unit - single-threaded execution with coroutine-based concurrency.

Quick Start

Build

docker build -t wordpress-trueasync .

Run

docker run -d \
  --name wordpress-async \
  -p 8080:8080 \
  wordpress-trueasync

Access

http://localhost:8080

How It Works

WordPress runs in a single process with concurrent request handling via coroutines:

HttpServer::onRequest(static function (Request $request, Response $response) {
    ob_start();
    
    try {
        include_once WP_ROOT . '/wp-load.php';

        wp();  // Each request runs as separate coroutine        
        
        if (defined('ABSPATH') && defined('WPINC')) {
            $template_loader = ABSPATH . WPINC . '/template-loader.php';
            include $template_loader;
        }
        
        $output = ob_get_clean();
        $response->setStatus(200);
        $response->write($output);
        $response->end();
    } catch (Throwable $e) {
        // Error handling
    }
});

Multiple requests are handled concurrently in the same PHP process using fiber-based coroutines.

Configuration

Default credentials:

• Database: trueasync
• User: trueasync
• Password: trueasync

Mount custom WordPress files:

docker run -d -p 8080:8080 -v $(pwd)/app:/app/www wordpress-trueasync

Purpose

This is a test environment to demonstrate coroutine-based concurrent request handling in WordPress with TrueAsync PHP.
