Nginx location for PHP files that do not exist - nginx

Question

I have config(minimal):
server {
listen test.local:80;
server_name test.local;
server_name_in_redirect off;
location / {
root /data/www/test/public;
try_files $uri $uri/ /index.php?route=$uri&$args;
index index.html index.php;
}
location ~ \.php$ {
root /data/www/test/public;
fastcgi_pass 127.0.0.1:9000;
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME /data/www/test/public$fastcgi_script_name;
fastcgi_param ...
...
}
}
Thats work file for urls /help/ or /contacts/ etc… (all redirect to index.php with get variables).
But if url, for example, /help.php or contacts.php, and this files not exists, I have output:
File not found.
How update my Nginx config? I need URLs, for example:
/help.php => /index.php?route=/help.php
/contacts.php?foo=bar... => /index.php?route=/contacts.php&args=…

Here is simple config for 404 error page . Its custom 404 page.
error_page 404 /404.php;
location /404.php {
root /var/www/public_html;
allow all;
}
Last part
Important line is ========== try_files $uri =404;
location ~ .php$ {
try_files $uri =404;
fastcgi_pass 127.0.0.1:9001;
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME /var/www/public_html$fastcgi_script_name;
include fastcgi_params;
}
