Problems moving Sites from Apache to Nginx (mod_rewrite) - php

Question

I am migrating some vhosts from apache to nginx. Unfortunately i am having some troubles because of .htaccess files from the apache instance.
Here is the situation (apache):
The DocumentRoot has different folders with projects inside. I could access most of them (through www.example.com/appname) without problems.
But on accessing (the main page) www.example.com the following .htaccess file redirects the users.
/var/www/html/.htaccess:
Redirect /index.html https://example.com/example/
Which then has another .htaccess in /var/www/html/example/.htaccess
Options -Indexes
IndexIgnore */*
Options FollowSymlinks
RewriteEngine on
RewriteRule ^(.+)?$ web/$1
So then the next .htaccess in /var/www/html/example/web
RewriteEngine on
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . index.php
How can i translate this to an nginx location block or blocks ? I can't seem to get it right. On my last check the client browser said that something is wrong with redirecting. Here is the nginx vhost config:
Please keep in mind that there are still some tries i found, but so far i didn't have any luck. Help would be really appreciated !
thank you guys

# FIRST .htaccess FILE

location /example/web {
# THIRD .htaccess FILE

# deny access to .htaccess files, if Apache's document root

check this out: Apache mod_rewrite to Nginx rewrite rules.
basically, apache rewrite and nginx rewrite do not quite mean the same thing. it seems that you are using nginx rewrite where you should be using nginx try_files.
so, you might try doing
try_files /web/$uri /web/$uri/ /web/index.php?$args
instead of
rewrite ^/(.+)?$ /web/$1;
