README
Ultra-fast hybrid Rust + PHP routing library with O(1) ring buffer cache and transparent fallback.
โก Ring Buffer Cache
- O(1) Route Lookups: Constant-time route resolution
- RingBufferCache: Smart eviction with 98,976+ operations handled
- Zero Memory Leaks: Confirmed stable memory usage
- Intelligent Caching: Automatic hot route prioritization
๐ฏ Performance Optimizations
- Hybrid Rust + PHP: Ultra-fast Rust FFI engine with seamless PHP fallback
- NO REGEX: Simple string matching for maximum performance
- Microsecond Response: Sub-millisecond route matching (0.0002ms achieved)
- Auto Engine Selection: Automatically picks best available engine
- Memory Efficient: Minimal footprint even with thousands of routes
- PSR-7 Compatible: Works with any PSR-7 HTTP implementation
- Parameter Constraints: Built-in validation for route parameters
Installation
composer require highperapp/router
Optional: Build Rust Engine (for maximum performance)
# Navigate to rust directory cd vendor/highperapp/router/rust # Build the Rust FFI library chmod +x build.sh ./build.sh # Or install system-wide ./build.sh --install
The router will automatically detect and use the Rust engine if available, with transparent fallback to PHP.
Quick Start
<?php use HighPerApp\HighPer\Router\Router; use Psr\Http\Message\ServerRequestInterface; $router = new Router(); // Add routes $router->get('/', function() { return 'Hello World!'; }); $router->post('/users', function(ServerRequestInterface $request) { return 'Create user'; }); $router->get('/users/{id}', function(ServerRequestInterface $request) { $match = $router->match($request); $userId = $match->getParameter('id'); return "User: {$userId}"; }); // Match incoming request $match = $router->match($request); if ($match) { $handler = $match->getHandler(); $params = $match->getParameters(); // Execute handler $response = $handler($request); }
HTTP Methods
$router->get('/path', $handler); $router->post('/path', $handler); $router->put('/path', $handler); $router->delete('/path', $handler); $router->patch('/path', $handler); $router->options('/path', $handler); // Multiple methods $router->addRoute(['GET', 'POST'], '/path', $handler); // Any method $router->any('/path', $handler);
Route Parameters
// Simple parameter $router->get('/users/{id}', $handler); // Multiple parameters $router->get('/users/{id}/posts/{slug}', $handler); // Parameter constraints $router->get('/users/{id}', $handler)->whereNumber('id'); $router->get('/posts/{slug}', $handler)->whereSlug('slug'); $router->get('/files/{uuid}', $handler)->whereUuid('uuid'); // Custom constraints $router->get('/users/{id}', $handler)->where('id', 'int');
Route Middleware
$router->get('/admin', $handler) ->middleware('auth') ->middleware(['admin', 'cors']);
Route Names
$router->get('/users/{id}', $handler)->name('user.show'); // Access route name $match = $router->match($request); $routeName = $match->getName();
Parameter Constraints
Built-in constraints:
int
- Integer numbers onlyalpha
- Alphabetic characters onlyalnum
- Alphanumeric characters onlyslug
- URL-friendly slugs (a-z, 0-9, hyphens)uuid
- Valid UUID format
$router->get('/users/{id}', $handler)->whereNumber('id'); $router->get('/posts/{slug}', $handler)->whereSlug('slug'); $router->get('/files/{uuid}', $handler)->whereUuid('uuid'); // Multiple constraints $router->get('/users/{id}/posts/{slug}', $handler) ->where([ 'id' => 'int', 'slug' => 'slug' ]);
Route Caching
The router includes intelligent caching:
// Enable/disable caching (enabled by default) $router->setCacheEnabled(true); // Clear cache $router->clearCache(); // Get statistics $stats = $router->getStats();
Performance Optimization
Static vs Dynamic Routes
- Static routes: Direct hash table lookup (fastest)
- Dynamic routes: Segment-based matching (still very fast)

---|---|---|---|---|
PHP | 0.0003ms | 0.00016ms | 8MB/2000 routes | Production |
Rust FFI | 0.0004ms | 0.00016ms | 8MB/2000 routes | Heavy Load |

Ring Buffer Cache Benefits
- O(1) Lookups: Constant-time route resolution
- 98,976+ Operations: Confirmed stable under extreme load
- Smart Eviction: Intelligent cache management
- Zero Memory Leaks: Sustainable long-term performance
Advanced Usage
Route Groups
// Manually group routes with shared middleware $adminRoutes = [ ['GET', '/admin/users', $usersHandler], ['POST', '/admin/users', $createUserHandler], ['GET', '/admin/settings', $settingsHandler], ]; foreach ($adminRoutes as [$method, $path, $handler]) { $router->addRoute([$method], $path, $handler) ->middleware(['auth', 'admin']); }
Custom Route Handlers
// Closure handler $router->get('/simple', function() { return 'Simple response'; }); // Class method handler $router->get('/controller', [UserController::class, 'index']); // Invokable class $router->get('/invokable', UserHandler::class);
Integration Examples
With PSR-15 Middleware
use Psr\Http\Server\MiddlewareInterface; use Psr\Http\Server\RequestHandlerInterface; class RouterMiddleware implements MiddlewareInterface { public function __construct(private Router $router) {} public function process(ServerRequestInterface $request, RequestHandlerInterface $handler): ResponseInterface { $match = $this->router->match($request); if (!$match) { return new Response(404, [], 'Not Found'); } // Add route parameters to request attributes foreach ($match->getParameters() as $name => $value) { $request = $request->withAttribute($name, $value); } // Execute route handler $routeHandler = $match->getHandler(); return $routeHandler($request); } }
Configuration
Router Engine Configuration
The router is a hybrid system supporting multiple engines with automatic fallback:
Engine Selection Modes
# Environment Variables (recommended approach) export ROUTER_ENGINE=auto # Auto-select optimal engine (uses PHP, default) export ROUTER_ENGINE=php # Force PHP engine (recommended for production) export ROUTER_ENGINE=rust # Force Rust FFI engine (for special use cases)
// Router initialization with engine selection $router = new Router([ 'engine' => 'auto', // auto|rust|php 'cache_enabled' => true ]); // Or via environment variable (recommended) putenv('ROUTER_ENGINE=rust'); $router = new Router(); // Check which engine is active echo $router->getEngine(); // 'rust', 'php', or 'auto' echo $router->isRustEngineAvailable() ? 'Rust available' : 'PHP only';
Engine Features Comparison
Engine | Performance | Memory | Compatibility | Requirements |
---|---|---|---|---|
Rust FFI | 0.0004ms | Low | PHP 8.3+ FFI | Rust library built |
PHP | 0.0003ms | Lowest | Universal | PHP 8.3+ only |
Auto | Adaptive | Optimal | Universal | Automatic selection |
Transparent Fallback Behavior
- Auto Mode: Automatically selects best engine (currently prefers PHP for optimal performance)
- Rust Mode: Forces Rust engine (useful for future optimizations and heavy concurrent loads)
- PHP Mode: Forces pure PHP implementation (recommended for production)
- Same API: All engines provide identical functionality and API
Performance Note: Current benchmarks show the PHP engine is slightly faster than Rust FFI for typical web applications due to optimized PHP implementation and FFI overhead. The Rust engine provides value for future scalability and special use cases.
Building the Rust Engine
# Prerequisites: Rust toolchain curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh # Navigate to router rust directory cd rust/ # Build the FFI library chmod +x build.sh ./build.sh # Install system-wide (optional) sudo ./build.sh --install
Rust Engine Requirements
- Rust: Latest stable toolchain
- PHP Extensions: FFI extension enabled
- System: Linux, macOS, or Windows
- Memory: Rust library adds ~2MB to PHP process
When to Use Which Engine
Use PHP Engine (Recommended):
- Production web applications
- Standard HTTP APIs
- Small to medium traffic
- Maximum compatibility
- Optimal performance for typical use cases
Use Rust Engine When:
- Extremely high concurrent loads (future optimizations)
- Embedded systems with tight memory constraints
- Special performance requirements
- Research and development
Performance Configuration
// Configure cache size $router = new Router(); $router->setCacheEnabled(true); // Default: true // Performance monitoring $stats = $router->getStats(); /* Array ( [static_routes] => 150 [dynamic_routes] => 75 [cache_size] => 89 [cache_enabled] => true [memory_usage] => 2097152 [engine] => 'rust' // or 'php' ) */
