Rewrite all requests to index.php with nginx

Question

In my apache configuration I have the following simple rewrite rule which

1. unless file exists will rewrite to index.php
2. on the urls you never see the file extension (.php)

how can I rewrite this in nginx?

#
# Redirect all to index.php
#
RewriteEngine On

# if a directory or a file exists, use it directly
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d

RewriteCond %{REQUEST_URI} (/[^.]*|\.)$ [NC]
RewriteRule .* index.php [L]

Here's how my nginx server block looks like now, but it doesn't work :(

root /home/user/www;
index index.php;

# Make site accessible from http://localhost/
server_name some-domain.dev;

# exclude /favicon.ico from logs
location = /favicon.ico {

    access_log off;

}   

# pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000
#   
location ~ \.php$ {
    fastcgi_split_path_info ^(.+\.php)(/.+)$;
    # NOTE: You should have "cgi.fix_pathinfo = 0;" in php.ini
    # With php5-cgi alone:
    fastcgi_pass 127.0.0.1:9000;
    fastcgi_index index.php;
    include fastcgi_params;
}

Answer 1

Perfect solution I have tried it and succeed to get my index page when I have append this code in my site configuration file.

location / {
            try_files $uri $uri/ /index.php;
}

In configuration file itself explained that at "First attempt to serve request as file, then as directory, then fall back to index.html in my case it is index.php as I am providing page through php code.
