Sample Silex app that has routing problem

app.php

// myapp/app/app.php


// ...

// route definitions
$app->mount('/myapp/subscribers', include 'controller/subscriber.php');


// later I tried these:

// this works
$app->get('/myapp/test/', function() {
    // do something
});

// these do not work
$app->get('/myapp/{var}/', function($var){
    // do something
});
$app->get('/myapp/test/{var}/', function($var){
    // do something
});


// ...

subscriber.php

// myapp/app/controller/subscriber.php


// ...

$subs = $app['controllers_factory'];

// this works
$subs->post('/', function (Application $app, Request $request) {
    // do something
});

// this does not work
$subs->match('/{mobile}/', function (Application $app, Request $request, $mobile) {
    $mobile = $app->escape($mobile);
    // do something
})->method('GET|PUT|DELETE');

// ...
