Zend Router Laravel Package

Getting Started

Start by installing the package via Composer: composer require zendframework/zend-router. Then, create a simple RouteStack and add basic routes—typically a Literal for static paths and a Segment for parameterized routes. For example:

use Zend\Router\Http\Literal;
use Zend\Router\Http\Segment;
use Zend\Router\RouteStack;

$router = new RouteStack();
$router->addRoute('home', new Literal([
    'route'    => '/',
    'defaults' => ['controller' => HomeController::class, 'action' => 'index'],
]));
$router->addRoute('user', new Segment([
    'route'    => '/user/:id',
    'defaults' => ['controller' => UserController::class, 'action' => 'view'],
    'constraints' => ['id' => '\d+'],
]));

Feed incoming $_SERVER data (e.g., request URI and method) into a ServerRequest and pass it to $router->match($request). The result contains matched route parameters (e.g., controller, action, id) ready for dispatch.

Implementation Patterns

• Middleware Integration: Use Zend\Stratigility\MiddlewareRunner with a route-matching middleware that injects the router. Matched route params can be injected into downstream middleware via request attributes.
• Named Route Linking: Use $router->assemble($name, $params) to generate URLs in templates or API responses—ensuring consistency when URLs change.
• Modular Routing: Build isolated route stacks per module or feature and merge them using RouteStack::addRoutes()—ideal for reusable packages.
• Constraint-Driven Matching: Leverage constraints on Segment routes for强类型 URL validation (e.g., UUIDs, dates) instead of relying on application logic.
• Priority Trees: Register high-priority routes (e.g., health checks, admin paths) first; routes added later are checked last, avoiding overlap issues.

Gotchas and Tips

• Finality of Matching: The router stops at the first matching route in the stack—even if later routes are more specific. Always order routes from most to least specific (e.g., /admin/users before /admin/:section).
• Default Values Matter: Unset defaults (e.g., no action key) may cause downstream dispatchers to fail; use defaults for required variables to guarantee predictable matches.
• URL Assembler Gotcha: assemble() doesn’t validate that params satisfy constraints—ensure your UI respects them (e.g., via form validation).
• No PSR-7/15 Out-of-the-Box: Though framework-agnostic, integration with PSR-15 middleware requires wrapping it in an adapter. The project is archived (2019), so consider modern forks like laminas/laminas-router for active support.
• Extending Routes: To support custom syntax (e.g., /api/{v} for versioned routes), subclass Zend\Router\Http\Literal or write a custom RouteInterface and register via plugin manager (available if extending laminas-mvc-style setups).
