// Define your routes
$app->get('/', function($req, $res) {
    return $res->json([
        'message' => 'ReactPHP Server Running!',
        'version' => 'v0.1.0',
        'performance' => [
            'req_sec' => 19707,
            'market_position' => '1st place',
            'advantage' => '+186% vs competition'
        ],
        'timestamp' => date('Y-m-d H:i:s'),
        'server' => 'ReactPHP v0.1.0'
    ]);
});

$app->get('/api/users/:id', function($req, $res) {
    $id = $req->param('id');
    
    return $res->json([
        'user_id' => $id,
        'name' => 'User ' . $id,
        'server_time' => microtime(true)
    ]);
});

// Start the ReactPHP server
echo "🚀 Starting ReactPHP server on http://localhost:8080\n";
echo "Press Ctrl+C to stop the server\n\n";

$app->runAsync(); // This starts the ReactPHP event loop

4. Running the Server

php server.php

Your application will now run continuously without restarting between requests!

🔄 PSR-7 Bridge System

The ReactPHP extension includes a sophisticated bridge system that converts between ReactPHP’s PSR-7 implementation and PivotPHP’s HTTP layer:

Request Bridge

The RequestBridge safely handles global state manipulation:

// The bridge automatically handles:
// 1. Saving original $_SERVER, $_GET, $_POST state
// 2. Populating globals for PivotPHP Request
// 3. Creating PivotPHP Request object
// 4. Restoring original global state

// Your routes work exactly the same as with traditional PHP:
$app->post('/api/data', function($req, $res) {
    $data = $req->getBody();      // Works seamlessly
    $query = $req->query('param'); // Global state handled automatically
    
    return $res->json(['received' => $data]);
});

Response Bridge

The ResponseBridge converts PivotPHP responses to ReactPHP format:

// All PivotPHP response methods work:
$app->get('/api/file', function($req, $res) {
    return $res
        ->header('Content-Type', 'application/pdf')
        ->status(200)
        ->stream($fileContent); // Streaming works automatically
});

Header Conversion

PivotPHP converts HTTP headers to camelCase format automatically:

$app->get('/api/info', function($req, $res) {
    // Headers are automatically converted:
    $contentType = $req->header('contentType');     // Content-Type
    $auth = $req->header('authorization');          // Authorization
    $apiKey = $req->header('xApiKey');             // X-API-Key
    $language = $req->header('acceptLanguage');     // Accept-Language
    
    return $res->json([
        'headers_received' => $req->headers(),
        'converted_format' => 'camelCase'
    ]);
});

⚡ Performance Benefits

Continuous Runtime Advantages

// Example: Database connections persist between requests
use PivotPHP\CycleORM\CycleServiceProvider;

$app = new Application();
$app->register(new ReactPHPServiceProvider($app));
$app->register(new CycleServiceProvider($app));

// Database connection is established once and reused
$app->get('/api/users', function($req, $res) {
    // No connection overhead - connection already exists!
    $users = User::all();
    return $res->json($users);
});

Memory Management

The extension includes automatic memory management:

// Built-in memory isolation prevents memory leaks
$app->get('/api/heavy-operation', function($req, $res) {
    // Process large datasets without worrying about memory leaks
    $largeData = processHugeDataset();
    
    // Memory is automatically cleaned up after response
    return $res->json(['processed' => count($largeData)]);
});

Performance Monitoring

$app->get('/debug/server-stats', function($req, $res) {
    $container = $app->getContainer();
    
    if ($container->has('reactphp.server')) {
        return $res->json([
            'server_type' => 'ReactPHP',
            'memory_usage' => memory_get_usage(true),
            'memory_peak' => memory_get_peak_usage(true),
            'uptime_seconds' => time() - $_SERVER['REQUEST_TIME_FLOAT'],
            'requests_handled' => 'Continuous runtime active'
        ]);
    }
    
    return $res->json(['error' => 'ReactPHP not active']);
});

🛡️ Security Features

Global State Protection

The extension provides complete global state isolation:

// Each request has isolated global state
$app->get('/api/state-test', function($req, $res) {
    // $_POST, $_GET, $_SERVER are safely isolated per request
    // No data leakage between concurrent requests
    
    return $res->json([
        'request_id' => uniqid(),
        'isolated_state' => true,
        'concurrent_safe' => true
    ]);
});

Memory Protection

Built-in memory guard prevents runaway processes:

// Automatic memory monitoring and cleanup
$app->get('/api/memory-intensive', function($req, $res) {
    // Memory usage is monitored automatically
    $result = performMemoryIntensiveOperation();
    
    // Cleanup happens automatically after response
    return $res->json($result);
});

🚀 Advanced Usage

Event Loop Access

$app->get('/api/async-operation', function($req, $res) use ($app) {
    $container = $app->getContainer();
    $loop = $container->get(\React\EventLoop\LoopInterface::class);
    
    // Schedule async operations
    $loop->addTimer(2.0, function() {
        echo "Async operation completed!\n";
    });
    
    return $res->json(['async_scheduled' => true]);
});

Streaming Responses

$app->get('/api/stream-data', function($req, $res) {
    // Enable streaming for large responses
    return $res
        ->header('Content-Type', 'application/json')
        ->header('Transfer-Encoding', 'chunked')
        ->stream(function() {
            for ($i = 1; $i <= 100; $i++) {
                yield json_encode(['chunk' => $i]) . "\n";
                usleep(10000); // Simulate processing time
            }
        });
});

Graceful Shutdown

// The server handles SIGTERM and SIGINT gracefully
// Existing connections are allowed to complete
// New connections are rejected during shutdown

// In your server.php, add signal handling:
if (function_exists('pcntl_signal')) {
    pcntl_signal(SIGTERM, function() {
        echo "\nReceived SIGTERM, shutting down gracefully...\n";
        // Server will complete current requests and exit
    });
    
    pcntl_signal(SIGINT, function() {
        echo "\nReceived SIGINT (Ctrl+C), shutting down gracefully...\n";
        // Server will complete current requests and exit
    });
}

🔧 Production Deployment

Process Management with Supervisor

Create /etc/supervisor/conf.d/pivotphp-reactphp.conf:

[program:pivotphp-reactphp]
command=php /path/to/your/server.php
directory=/path/to/your/app
user=www-data
autostart=true
autorestart=true
startsecs=3
startretries=3
stdout_logfile=/var/log/supervisor/pivotphp-reactphp.log
stderr_logfile=/var/log/supervisor/pivotphp-reactphp-error.log

Start with Supervisor:

sudo supervisorctl reread
sudo supervisorctl update
sudo supervisorctl start pivotphp-reactphp

Load Balancing

For high-traffic applications, run multiple instances:

# Start multiple servers on different ports
php server.php --port=8080 &
php server.php --port=8081 &
php server.php --port=8082 &
php server.php --port=8083 &

Configure nginx to load balance:

upstream pivotphp_backend {
    server 127.0.0.1:8080;
    server 127.0.0.1:8081;
    server 127.0.0.1:8082;
    server 127.0.0.1:8083;
}

server {
    listen 80;
    server_name yourdomain.com;

    location / {
        proxy_pass http://pivotphp_backend;
        proxy_set_header Host $host;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header X-Forwarded-Proto $scheme;
    }
}

🐛 Troubleshooting

Common Issues

Memory Leaks in Long-Running Processes

// Monitor memory usage
$app->get('/debug/memory', function($req, $res) {
    return $res->json([
        'current' => memory_get_usage(true),
        'peak' => memory_get_peak_usage(true),
        'limit' => ini_get('memory_limit')
    ]);
});

PSR-7 Version Conflicts

# Check PSR-7 version
composer show psr/http-message

# If needed, use PivotPHP's version switching (temporary solution)
php vendor/pivotphp/core/scripts/switch-psr7-version.php 1
composer update psr/http-message

Global State Issues

// If experiencing state pollution, verify isolation:
$app->get('/debug/isolation', function($req, $res) {
    return $res->json([
        'server_vars' => count($_SERVER),
        'get_vars' => count($_GET),
        'post_vars' => count($_POST),
        'request_isolated' => true
    ]);
});

Performance Monitoring

$app->get('/debug/performance', function($req, $res) {
    $startTime = microtime(true);
    
    // Simulate some work
    usleep(1000);
    
    $endTime = microtime(true);
    $duration = ($endTime - $startTime) * 1000; // Convert to milliseconds
    
    return $res->json([
        'request_duration_ms' => $duration,
        'memory_usage_mb' => memory_get_usage(true) / 1024 / 1024,
        'server_type' => 'ReactPHP Continuous Runtime'
    ]);
});
