A PHP routing library based on a tree structure

Why SimpleRoute?

Traditional PHP routers (like Laravel or Symfony) use flat arrays to define routes.

Problem: With nested routes, the code quickly becomes repetitive and harder to maintain:

// Classic router
$routes = [
    '/api/users' => $usersHandler,
    '/api/users/profile' => $profileHandler,
    '/api/users/settings' => $settingsHandler,
];

Solution: SimpleRoute uses a tree structure that naturally reflects the hierarchy of URLs.

You can build your route tree in two ways 👇

🧱 Classic method (explicit)

$root->addChild($api);
$api->addChild($users);
$users->addChild($profile);
$users->addChild($settings);

⚡ Simplified method (modern)

$root = new Node('root');
$api = new Node('api', parent: $root);
$users = new Node('users', parent: $api);
$profile = new Node('profile', parent: $users);
$settings = new Node('settings', parent: $users);

Result: Cleaner code, no duplication, and a clear visual hierarchy.

✨ Features

• 🌳 Tree-based structure – Routes are organized hierarchically (parent/child), just like real URLs
• ⚡ O(h) performance – Fast route lookup based on tree depth
• ✅ 119 unit tests – Reliable code with high coverage
• 🧠 Type-safe (PHP 8.1+) – Full type hints to prevent runtime errors
• 🧩 Typed exceptions – Each error has its own class for easier debugging
• 🪶 Lightweight – Zero external dependencies

🚀 Installation

Via Composer (recommended)

composer require akido-ld/simple-route

Manual installation (for contributors)

git clone https://github.com/AkidoLD/SimpleRoute.git
cd SimpleRoute
composer install

🧩 Usage Example

use SimpleRoute\Router\{Node, NodeTree, Router, UriSlicer};

// Create nodes
$root = new Node('root');
$api = new Node('api', parent: $root);
$users = new Node('users', function() {
    echo json_encode(['users' => ['Alice', 'Bob']]);
}, parent: $api);

// Router setup
$tree = new NodeTree($root);
$router = new Router($tree);

// Match an URL
$uri = new UriSlicer('/api/users');
$router->dispatch($uri);

// Output: {"users":["Alice","Bob"]}
