nginx redirect loop, remove index.php from url

Great question, with the solution similar to another one I've answered on ServerFault recently, although it's much simpler here, and you know exactly what you need.

What you want here is to only perform the redirect when the user explicitly requests /index.php, but never redirect any of the internal requests that end up being served by the actual index.php script, as defined through the index directive.

This should do just that, avoiding the loops:

server {
    index index.php;

    if ($request_uri ~* "^(.*/)index\.php$") {
        return 301 $1;
    }

    location / {

        # ...
    }
}

Try that

location ~ /*/index.php {
    rewrite ^/(.*)/(.*) http://www.votre_domaine.com/$1 permanent;
}
location /index.php {
    return 301 http://www.example.com/;
}

If you already have first line mentioned below in your Nginx configuration file you don't have rewrite it again.

index index.php index.html index.htm;

rewrite ^(/.).html(?.)?$ $1$2 permanent;

rewrite ^/(.*)/$ /$1 permanent;

try_files $uri/index.html $uri.html $uri/ $uri =404;

This will remove .html from the URL and additionally will also remove "index" from home page or index page. For example - https://www.example.com/index will be changed to https://www.example.com
