How to remove both .php and .html extensions from url using NGINX?

From what I've researched, if you append your /etc/nginx/conf.d/domain.tld.conf file to include:

location / {
    try_files $uri $uri.html $uri/ @extensionless-php;
    index index.html index.htm index.php;
}

location ~ \.php$ {
    try_files $uri =404;
}

location @extensionless-php {
    rewrite ^(.*)$ $1.php last;
}

Then restart nginx and give it a go. Hopefully this will help you! More information can be found (where I found it) here @ tweaktalk.net

No need for extra blocks and named locations and everything. Also move the index line outside the location block

server {
  index index.html index.php;
  location / {
    try_files $uri $uri/ $uri.html $uri.php$is_args$query_string;
  }
  location ~ \.php$ {
    try_files $uri =404;
    # add fastcgi_pass line here, depending if you use socket or port
  }
}

Keep in mind that if you have a folder and a file with the same name inside the same folder, like /folder/xyz/ and /folder/xyz.php you won't be able to run the php file if the folder xyz contains an index.php or index.html, just keep this in mind.
