Heroku silex route show 404 except "/" - php

Question

This piece of code was from an example at heroku. But except the route /, anything else I add does not work. It shows 404:
The requested URL /e was not found on this server.
$app->match('/', function(Symfony\Component\HttpFoundation\Request $request) use ($app) {
return $app['twig']->render('index.twig');
});
$app->match("/dump", function(Symfony\Component\HttpFoundation\Request $request) use ($app) {
return new Response('Thank you for your feedback!', 201);
})->bind("dump");
$app->get("/t", function() use ($app) {
return new Response('Thank you for your feedback!', 201);
})->bind("t");
$app->get("/d", function() {
return new Response('Thank you for your feedback!', 201);
})->bind("d");
$app->get("/e", function() {
return new Response('Thank you for your feedback!', 201);
});
$app->run();
Edit 1
I deployed it directly on heroku server (heroku auto build on each push to master branch)
Edit 2
my workspace:
bin\worker.php
www\index.php <== the snippet is from this file
www\list.php
apache_app.conf
app.php <== basic init, return Silex\Application $app
Procfile
The content of apache_app.conf is copied from this link.
RewriteEngine On
RewriteCond %{REQUEST_URI}::$1 ^(/.+)/(.*)::\2$
RewriteRule ^(.*) - [E=BASE:%1]
RewriteCond %{ENV:REDIRECT_STATUS} ^$
RewriteRule ^app\.php(/(.*)|$) %{ENV:BASE}/$2 [R=301,L]
RewriteCond %{REQUEST_FILENAME} -f
RewriteRule .? - [L]
RewriteRule .? %{ENV:BASE}/app.php [L]
I figured that I need to change the apache config somehow, but I don't understand htaccess syntax.

For apache2, you can add a .htaccess file within "/web"
<IfModule mod_rewrite.c>
Options -MultiViews
RewriteEngine On
#RewriteBase /path/to/app
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^ index.php [QSA,L]
</IfModule>
and set your Procfile as:
web: vendor/bin/heroku-php-apache2 web/
For nginx, create a nginx conf file with content:
location / {
# try to serve file directly, fallback to rewrite
try_files $uri #rewriteapp;
}
location #rewriteapp {
# rewrite all to index.php
rewrite ^(.*)$ /index.php/$1 last;
}
location ~ ^/(index|index_dev)\.php(/|$) {
try_files #heroku-fcgi #heroku-fcgi;
internal;
}
and set Procfile as:
web: vendor/bin/heroku-php-nginx -C server_conf/nginx.conf web/

It's very simple, just install apache :
composer require apache-pack

Answer 3

I had the same issue, and it stumped me for weeks... to the point where I just started using / as my only route and adding other capability through passed-in variables. Drove me up the wall.
I finally had the need to fix it for real, and after a few hours found this post:
https://laracasts.com/discuss/channels/laravel/laravel-v5415-on-heroku-all-routes-but-not-working
TL/DR; I had duplicated a (correctly working) heroku repo to create my new one, and somewhere along the way my web/.htaccess file got deleted. I replaced it, and everything works like a charm.
For me the provided test also worked well (I'm using PHP): if eaxmple.com/ROUTE doesn't work, but example.com/index.php/ROUTE does work... you have an .htaccess problem.
Also, for reference, here's my entire .htaccess file:
RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^ index.php [QSA,L]
Hopefully this saves someone some searching...
