PHP 快速需求路由：FastRoute

FastRoute 提供了一个快速实现基于路由的规则表达。

示例代码：

<?phprequire '/path/to/FastRoute/src/bootstrap.php';$dispatcher = FastRoute\simpleDispatcher(function(FastRoute\RouteCollector $r) {    $r->addRoute('GET', '/user/{id:\d+}', 'handler1');    $r->addRoute('GET', '/user/{id:\d+}/{name}', 'handler2');    // Or alternatively    $r->addRoute('GET', '/user/{id:\d+}[/{name}]', 'common_handler');});$routeInfo = $dispatcher->dispatch($httpMethod, $uri);switch ($routeInfo[0]) {    case FastRoute\Dispatcher::NOT_FOUND:        // ... 404 Not Found        break;    case FastRoute\Dispatcher::METHOD_NOT_ALLOWED:        $allowedMethods = $routeInfo[1];        // ... 405 Method Not Allowed        break;    case FastRoute\Dispatcher::FOUND:        $handler = $routeInfo[1];        $vars = $routeInfo[2];        // ... call $handler with $vars        break;}
