nginx rewrite rules for Codeigniter are not working correctly

Question

I am trying to use nginx server in MAMP instead of apache server for Codeigniter for the first time. I converted my apache htaccess rewrite rules to nginx rewrite rules. But it is showing index.php file code from my file not my website. Here is my apache htaccess rules,

DirectoryIndex index.php
RewriteEngine on
RewriteCond $1 !^(index\.php|images|css|js|robots\.txt|favicon\.ico)
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ ./index.php/$1 [L,QSA]

And here is my nginx configuration file,

http {
include                  mime.types;
default_type             text/html;
gzip                     on;
gzip_types               text/css text/x-component application/x-javascript application/javascript text/javascript text/x-js text/richtext image/svg+xml text/plain text/xsd text/xsl text/xml image/x-icon;

sendfile                 on;

server {
    listen               80 default_server;

    # MAMP DOCUMENT_ROOT !! Don't remove this line !!
    root "C:/MAMP/htdocs/aia_inventory/";

    access_log  C:/MAMP/logs/nginx_access.log;

    error_log  C:/MAMP/logs/nginx_error.log;

    index index.html index.htm index.php;
    #autoindex on;
    #server_name localhost;
    location ~/ {
        #root C:/MAMP/htdocs/aia_inventory/;
        #index index.html index.php;
        try_files $uri $uri/ /index.php/$request_uri;

        if (!-e $request_filename){
            rewrite ^/(.*)$ /index.php?/$1 last;
            break;
        }
    }

    location ~* ^/(assets|files|robots\.txt) { }

    # }

    # location ~* \.(txt|log)$ {

    #   deny all;
    # }

    # location ~ \..*/.*\.php$ {
    #   return 403;
    # }

    #location /nginx_status {
    #   stub_status      on;
    #   access_log       off;
    #   allow            127.0.0.1;
    #   deny             all;
    #}
}
}

I am not understanding where am I missing. My rules are working on apache server. But on nginx server, it shows only index.php file raw code. Thanks in advance.

Answer 1

Sorry for the late answer. It was actually very silly mistake. My controller page name was in small character. This is why it was not working. My configuration is okay. The first letter of the controller page should be in capital character. For example, my controller name is Home. So my php file name must be Home.php not home.php. It will work on local ngincx server but not in live server.
