I'm attempting to use the FastRoute routing library and can't get the simple usage example to work.
Here is the basic usage example found on the GitHub page:
<?php
require '/path/to/vendor/autoload.php';
$dispatcher = FastRoute\simpleDispatcher(function(FastRoute\RouteCollector $r) {
$r->addRoute('GET', '/users', 'get_all_users_handler');
// {id} must be a number (\d+)
$r->addRoute('GET', '/user/{id:\d+}', 'get_user_handler');
// The /{title} suffix is optional
$r->addRoute('GET', '/articles/{id:\d+}[/{title}]', 'get_article_handler');
});
// Fetch method and URI from somewhere
$httpMethod = $_SERVER['REQUEST_METHOD'];
$uri = $_SERVER['REQUEST_URI'];
// Strip query string (?foo=bar) and decode URI
if (false !== $pos = strpos($uri, '?')) {
$uri = substr($uri, 0, $pos);
}
$uri = rawurldecode($uri);
$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;
}
Where the comment reads "... call $handler with $vars", I've tried returning call_user_func_array($handler, $vars) but it doesn't work.
I also thought that maybe it was the .htaccess file that was stopping it working, as the Github page doesn't have a .htaccess file example for the project. I'm using this:
RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . index.php [QSA,L]
I've also tried calling a route with a closure as the handler, like so:
$r->addRoute('GET', '/', function() {
echo 'home';
});

Example how to handle request
$r->addRoute('GET', '/users', 'User/getUsers');
Then if dispatcher found, you can process it like following
case FastRoute\Dispatcher::FOUND:
$handler = $routeInfo[1];
$vars = $routeInfo[2];
list($class, $method) = explode("/", $handler, 2);
call_user_func_array(array(new $class, $method), $vars);
break;
Don't forget to create class User with getUsers() method.
