Set up symfony4 URI with ONLY .htaccess - .htaccess

Question

I am launching a symfony website on a server that can't be configured at all. So I can't touch the apache conf and all, I only have access to the drop repository.
So I need to use ONLY htaccess to :
point to the "public/index.php" file
Remove the "public" part from the url
I now have succeded the 1rst part with this in my lowest level .htaccess:
DirectoryIndex public/index.php public/index.html
My second .htaccess is the basic one:
# Use the front controller as index file. It serves as a fallback solution when
# every other rewrite/redirect fails (e.g. in an aliased environment without
# mod_rewrite). Additionally, this reduces the matching process for the
# start page (path "/") because otherwise Apache will apply the rewriting rules
# to each configured DirectoryIndex file (e.g. index.php, index.html, index.pl).
DirectoryIndex index.php
# By default, Apache does not evaluate symbolic links if you did not enable this
# feature in your server configuration. Uncomment the following line if you
# install assets as symlinks or if you experience problems related to symlinks
# when compiling LESS/Sass/CoffeScript assets.
# Options FollowSymlinks
# Disabling MultiViews prevents unwanted negotiation, e.g. "/index" should not resolve
# to the front controller "/index.php" but be rewritten to "/index.php/index".
<IfModule mod_negotiation.c>
Options -MultiViews
</IfModule>
<IfModule mod_rewrite.c>
RewriteEngine On
# Determine the RewriteBase automatically and set it as environment variable.
# If you are using Apache aliases to do mass virtual hosting or installed the
# project in a subdirectory, the base path will be prepended to allow proper
# resolution of the index.php file and to redirect to the correct URI. It will
# work in environments without path prefix as well, providing a safe, one-size
# fits all solution. But as you do not need it in this case, you can comment
# the following 2 lines to eliminate the overhead.
RewriteCond %{REQUEST_URI}::$1 ^(/.+)/(.*)::\2$
RewriteRule ^(.*) - [E=BASE:%1]
# Sets the HTTP_AUTHORIZATION header removed by Apache
RewriteCond %{HTTP:Authorization} .
RewriteRule ^ - [E=HTTP_AUTHORIZATION:%{HTTP:Authorization}]
# Redirect to URI without front controller to prevent duplicate content
# (with and without `/index.php`). Only do this redirect on the initial
# rewrite by Apache and not on subsequent cycles. Otherwise we would get an
# endless redirect loop (request -> rewrite to front controller ->
# redirect -> request -> ...).
# So in case you get a "too many redirects" error or you always get redirected
# to the start page because your Apache does not expose the REDIRECT_STATUS
# environment variable, you have 2 choices:
# - disable this feature by commenting the following 2 lines or
# - use Apache >= 2.3.9 and replace all L flags by END flags and remove the
# following RewriteCond (best solution)
RewriteCond %{ENV:REDIRECT_STATUS} ^$
RewriteRule ^index\.php(?:/(.*)|$) %{ENV:BASE}/$1 [R=301,L]
# If the requested filename exists, simply serve it.
# We only want to let Apache serve files and not directories.
RewriteCond %{REQUEST_FILENAME} -f
RewriteRule ^ - [L]
# Rewrite all other queries to the front controller.
RewriteRule ^ %{ENV:BASE}/index.php [L]
</IfModule>
<IfModule !mod_rewrite.c>
<IfModule mod_alias.c>
# When mod_rewrite is not available, we instruct a temporary redirect of
# the start page to the front controller explicitly so that the website
# and the generated links can still be used.
RedirectMatch 307 ^/$ /index.php/
# RedirectTemp cannot be used instead
</IfModule>
</IfModule>
How can I do the second part ?

Answer 1

I believe you are solving things the other way around. The proper solution is described here https://medium.com/#runawaycoin/deploying-symfony-4-application-to-shared-hosting-with-just-ftp-access-e65d2c5e0e3d
Upload the following folders (and contents) from your application to a new folder in your root of your FTP server named symfony:
bin
config
src
templates
translations
vendor
Note: Only upload the bin folder if you want to run the console, maybe via a cron job, also best to rename console to console.php
Also create the var folder but dont upload its contents.
And upload your composer.json file to this symfony folder — this is needed to help symfony find its application files.
So you should have this on your server:
\symfony
bin
config
src
templates
translations
vendor
composer.json
\public_html
index.php
.htaccess
bundles
build
Dont forget that you will need to modify index.php
Before your application will work you need to modify your index.php file and set your env vars.
First edit your index.php (locally inside your public folder, on the server will be inside your public_html folder).
Edit this line:
require __DIR__.’/../vendor/autoload.php’;
To:
require __DIR__.’/../symfony/vendor/autoload.php’;
