Apache RewriteRule in htaccess - Routes are broken

Question

I have a simple structure:

Root
|-- [app] (Symfony Application)
|    |-- [app]
|    |-- [bin]
|    |-- [src]
|    |-- [vendor]
|    |-- [web]
|         |-- .htaccess (Symfony htaccess)
|
|-- [wp-admin]
|-- [wp-content]
|-- [wp-include]
|-- .htaccess (Root htaccess)

I need following mapping:

http://example.com      ==> Wordpress 
http://example.com/app  ==> Symfony Application

This is what I have:

Root htaccess:

<IfModule mod_rewrite.c>
    RewriteEngine On
    RewriteRule ^app(.*)$ app/web/$1 [L,QSA]
    RewriteBase /
    RewriteRule ^index\.php$ - [L]
    RewriteCond %{REQUEST_FILENAME} !-f
    RewriteCond %{REQUEST_FILENAME} !-d
    RewriteRule . /index.php [L]
</IfModule>

Symfony htaccess:

DirectoryIndex app.php

<IfModule mod_negotiation.c>
    Options -MultiViews
</IfModule>

<IfModule mod_rewrite.c>
    RewriteEngine On
    RewriteCond %{REQUEST_URI}::$1 ^(/.+)/(.*)::\2$
    RewriteRule ^(.*) - [E=BASE:%1]
    RewriteCond %{HTTP:Authorization} .
    RewriteRule ^ - [E=HTTP_AUTHORIZATION:%{HTTP:Authorization}]
    RewriteCond %{ENV:REDIRECT_STATUS} ^$
    RewriteRule ^app\.php(?:/(.*)|$) %{ENV:BASE}/$1 [R=301,L]
    RewriteCond %{REQUEST_FILENAME} -f
    RewriteRule ^ - [L]
    RewriteRule ^ %{ENV:BASE}/app.php [L]
</IfModule>

<IfModule !mod_rewrite.c>
    <IfModule mod_alias.c>
        RedirectMatch 302 ^/$ /app.php/
    </IfModule>
</IfModule>

Problem:

The problem is that, Symfony routes are not resolved:

No route found for "GET /"

Is there any simple solution to this?

Answer 1

This solution requires ssh access.

Abandon all solutions based on htaccess rules . Try to use symbolic link instead ln -s command

The best idea here is to put each project in seperate folder otuside folder where your domain is pointing (let's name it here as public_html)

ROOT
|
-[Symfony]
-[WP]
-[public_html] (folder where your domain is pointing) 

and now - remove public_html - add symbolic link to wp ( with name of public html) - include wp create symbolic link to symfony/web

ROOT
|
-[Symfony]
-[WP]
-- [app]  (symbolic link to symfony/web)
-[public_html] (symbolic link to WP ) 

As alternative i think that possible is to redirect request from symfony to wp and then push wp response to user(from symfony) . I seen solutions like this ( it's used when you building new app on top of legacy system ) . But this is more problematic than symbolic link ( you can see the idea here https://www.enotogorsk.ru/en/2014/07/22/symfony-legacy-bridge/)
