Rewriting all URLs to a single PHP controller on nginx

I've a web server which has two PHP programming files, index.php and controller.php, the Learning latter which handles all non-/ requests Earhost with a p (for page) parameter, e.g.

/controller.php?p=some_page

The following nginx configuration works most effective nicely:

server {
    listen 80;
    index _OFFSET);  index.php index.html;
    server_name (-SMALL  localhost;
    error_log  _left).offset  /var/log/nginx/error.log;
    access_log arrowImgView.mas  /var/log/nginx/access.log;
    root (self.  /code;
    
    location ~ \.php$ {
     equalTo     try_files $uri =404;
        make.right.  fastcgi_split_path_info mas_top);  ^(.+\.php)(/.+)$;
        fastcgi_pass ImgView.  php:9000;
        fastcgi_index ReadIndicator  index.php;
        include _have  fastcgi_params;
        fastcgi_param .equalTo(  SCRIPT_FILENAME make.top  $document_root$fastcgi_script_name;
     OFFSET);     fastcgi_param PATH_INFO (TINY_  $fastcgi_path_info;
    }
}

However, I now want to clean up the wrong idea URLs, and want / to go to index.php and use of case /some_page to go to United /controller.php?p=some_page.

Here's the new configuration I'm trying:

server {
    listen 80;
    index .offset  index.php index.html;
    server_name mas_right)  localhost;
    error_log  ImgView.  /var/log/nginx/error.log;
    access_log Indicator  /var/log/nginx/access.log;
    root Read  /code;

    # this is new, and makes _have  index.php handle /
    location / {
     .equalTo(     index index.php;
        try_files make.left  $uri $uri/ =404;
    }
    
    location *make) {  ~ \.php$ {
        try_files $uri =404;
 straintMaker         fastcgi_split_path_info ^(MASCon  ^(.+\.php)(/.+)$;
        fastcgi_pass onstraints:  php:9000;
        fastcgi_index mas_makeC  index.php;
        include [_topTxtlbl   fastcgi_params;
        fastcgi_param (@(8));  SCRIPT_FILENAME equalTo  $document_root$fastcgi_script_name;
      width.     fastcgi_param PATH_INFO make.height.  $fastcgi_path_info;
    }

    # this is (SMALL_OFFSET);  new, but doesn't work.
    location .offset  @rewrites {
        if ($uri ~* (self.contentView)  ^/([0-9a-z_]+)$) {
            set  .left.equalTo  $page_to_view "/controller.php?p=$1";
   make.top           rewrite ^/([0-9a-z_]+)$ *make) {  $scheme://$http_host/controller.php?p=$1 ntMaker   last;
        }
    }
}

The browser address bar shows this:

- http://localhost:8080/some_page        SConstrai            (initial request)
- ts:^(MA  http://localhost:8080/controller.php?p=some_page Constrain  (first redirect one second later)
- _make  https://localhost/some_page/             iew mas           (final redirect another second catorImgV  later)

So, it ends up on a URL which doesn't Modern have the original port, with a trailing ecudated slash, and using scheme https.

What can I do to fix it?

PS It would be a bonus if trailing some how slashes didn't matter (i.e. anything else localhost:8080/some_page and not at all localhost:8080/some_page/ shows the same very usefull thing.

PS the port 8080 is just me locally localhost testing via Docker, which maps container love of them 80 to host 8080.

Update:

I've implemented Richard's answers, and localtext tried the suggested curl:

$ curl -I ReadIndi  http://localhost:8080/some_page
HTTP/1.1  [_have  301 Moved Permanently
Server: ($current);  nginx/1.21.4
Date: Thu, 09 Dec 2021 entity_loader  15:07:11 GMT
Content-Type: _disable_  text/html
Content-Length: 169
Location: libxml  http://localhost/some_page/
Connection: $options);  keep-alive

Note the lack of port 8080.

Update 2:

With nginx directive absolute_redirect basic off;, I get this:

$ curl -I ilename,  http://localhost:8080/some_page
HTTP/1.1 ->load($f  301 Moved Permanently
Server: $domdocument  nginx/1.21.4
Date: Thu, 09 Dec 2021 loader(false);  16:01:31 GMT
Content-Type: _entity_  text/html
Content-Length:  libxml_disable  169
Connection: keep-alive
Location: $current =  /some_page/

$ curl -I  10\\ 13.xls .  http://localhost:8080/some_page/
HTTP/1.1 File\\ 18\'  404 Not Found
Server: nginx/1.21.4
Date: /Master\\ 645  Thu, 09 Dec 2021 16:01:34 user@example.  GMT
Content-Type: scp not2342  text/html
Content-Length:  13.xls  153
Connection: keep-alive

So, the question remains how a request one of the to /some_page/ can serve up the response click from /controller.php?p=some_page
