The .htaccess example for Symfony Framework project that deployed on shared hosting.

.htaccess

#path/to/project/.htaccess

# Rewrite all requests to subdirectory, except exists file requests
<IfModule mod_rewrite.c>
    RewriteEngine On
    RewriteCond %{REQUEST_FILENAME} !-f
    RewriteRule ^(.*)$ /web/$1 [QSA,L]
</IfModule>

web.htaccess

#path/to/project/web/.htaccess

# Remove subdirectory and app.php file from request URI
<IfModule mod_rewrite.c>
    RewriteEngine On
    RewriteCond %{THE_REQUEST} ^[A-Z]{3,9}\ /(app\.php|app_dev\.php|config\.php|web/(?!app_dev\.php|config\.php))
    RewriteRule ^(app\.php|app_dev\.php|config\.php)?/?(.*)$ /$2 [R=301,L]
</IfModule>

Not working for me.. URL not found error

Work!!!! thank you very much

Going through all those scripts just to deploy symfony on shared hosting is quite a pain. I would recommend hosting PHP based apps, like symfony on a cloud server using PaaS, like Cloudways. This PHP MySQL web hosting platform lets users automatically setup server in one click. Once the server is ready, user can install Symfony using composer and deploy app from github.
