Swoole HTTP Server: Overview and Implementation

Swoole is a high-performance PHP extension for building asynchronous, event-driven, and concurrent network servers、Its HTTP server component is ideal for building fast, scalable web applications without relying on traditional PHP-FPM + Nginx setups.

1、Installation
Prerequisites:
PHP 7.2+ (Swoole 4.8+ requires PHP 7.2+)
`libpcre3-dev`, `libssl-dev` (for Ubuntu/Debian), or equivalent for your OS.

Steps:
bash
Install dependencies
sudo apt-get install libpcre3-dev libssl-dev

Install Swoole via PECL
pecl install swoole

Enable the extension in php.ini
echo extension=swoole.so /etc/php/7.4/cli/php.ini Adjust PHP version as needed

Verify Installation:
php
<?php
var_dump(extension_loaded('swoole')); // Should return true

2、Basic HTTP Server Example
Create a file `server.php`:
php
<?php
use Swoole\Http\Server;
use Swoole\Http\Request;
use Swoole\Http\Response;

$server = new Server('0.0.0.0', 9501);

// Set configuration (optional)
$server-set([
'worker_num' = 4, // Number of worker processes
'max_request' = 10000, // Max requests per worker
]);

// Handle HTTP requests
$server-on('request', function (Request $request, Response $response) {
$response-header('Content-Type', 'text/html');
$response-end('<h1Hello, Swoole!</h1');
});

$server-start();

Run the Server:
bash
php server.php

Access:
Open `http://localhost:9501` in your browser、
Output: `Hello, Swoole!`

3、Key Features & Configuration
a) Routing Logic
Handle different routes manually (Swoole doesn't include a built-in router):
php
$server-on('request', function (Request $request, Response $response) {
$uri = $request-server['request_uri'];

if ($uri === '/api/data') {
$response-json(['data' = 'example']);
} else {
$response-end('404 Not Found');
}
});

b) Request Data Handling
GET: `$request-get['key']`
POST: `$request-post['key']`
Body: `$request-rawContent()`
Files: `$request-files['file']`

c) Advanced Configuration
php
$server-set([
'daemonize' = true, // Run as a daemon (background process)
'log_file' = '/var/log/swoole.log',
'task_worker_num' = 2, // For task handling
'ssl_cert_file' = '/path/to/cert.pem', // For HTTPS
'ssl_key_file' = '/path/to/key.pem'
]);

4、Common Use Cases
High-traffic APIs: Swoole's event-driven model handles 10k+ concurrent connections.
Real-time Applications: Combined with WebSocket (Swoole supports WebSocket natively).
Microservices: Run as a standalone service without Nginx.

5、Debugging Tips
Check Logs: Use `Swoole\Runtime::setLogger(...)` for custom logging.
Port Conflicts: Ensure port `9501` (or your chosen port) is free.
Debugging Mode: Run without `daemonize` for real-time error visibility:
php
$server-set(['daemonize' = false]);

6、Why Swoole?
Performance: 10x faster than PHP-FPM for I/O-bound tasks.
Concurrency: Asynchronous I/O, no blocking during network operations.
Simplicity: No need for Nginx/Apache configuration for basic use cases.

7、Next Steps
Learn Swoole Coroutines: For async operations (e.g., database calls).
Use Swoole Frameworks: `Swoole-Http-Server` or `Swoole-WebSocket-Server` for advanced features.
Security: Always validate input and sanitize responses.

Note: For production, use a process manager (e.g., `supervisor`) to restart the server on failure.

Let me know if you need help with a specific scenario (e.g., WebSocket, database integration)! 🚀
