Nginx rewrite path to query string - php

Question

I use nginx (php-fpm) and fatfree framework. I need some redirect logic in my routing engine. It looks like:
http://example.net/page/...
Instead of dots there could be something like:
another.net/someurl
http://another.net/?local_query
another.net/path/to/article.html
It breaks nginx logic and I see 404 error.
My nginx config looks simply:
location / {
try_files $uri $uri/ /index.php?$args;
}
location ~ \.php$ {
include /etc/nginx/conf.d/fastcgi_params.conf;
fastcgi_param SCRIPT_FILENAME /var/www/$main_host/www$fastcgi_script_name;
fastcgi_param DOCUMENT_ROOT /var/www/$main_host/www;
fastcgi_param PHP_ADMIN_VALUE upload_tmp_dir=/var/www/$main_host/tmp/upload;
fastcgi_param PHP_ADMIN_VALUE session.save_path=/var/www/$main_host/tmp/sessions;
}
So when I use:
http://example.net/page/another.net/path/to/article.html
Nginx tries to find file in filesystem with name article.html as I understand. How to write rule to ignore any symbols when there is keyword page after domain?

Solution #1:
Probably it doesn't work because there is no fastcgi_pass directive inside /etc/nginx/conf.d/fastcgi_params.conf.
If so, all you need is simply add it to your \.php$ location. In general case it looks like:
fastcgi_pass 127.0.0.1:9000;
but this line might be different, depending on how PHP-FPM is configured.
Solution #2:
Your current configuration makes Nginx pass request to PHP-FPM only if URI ends with .php.
To make Nginx do it when URI starts with /page/ as well, you should write a new location with almost the same content (except for SCRIPT_FILENAME line) and (important!) put it before existing \.php$ location.
Copying location content would cause a code duplication, and I would recommend write the config in a slightly different way:
fastcgi_param SCRIPT_FILENAME /var/www/$main_host/www$my_script_name;
fastcgi_param DOCUMENT_ROOT /var/www/$main_host/www;
fastcgi_param PHP_ADMIN_VALUE upload_tmp_dir=/var/www/$main_host/tmp/upload;
fastcgi_param PHP_ADMIN_VALUE session.save_path=/var/www/$main_host/tmp/sessions;
include /etc/nginx/conf.d/fastcgi_params.conf;
location ~ /page/ {
fastcgi_pass 127.0.0.1:9000;
set $my_script_name /path/to/file.php;
}
location ~ \.php$ {
fastcgi_pass 127.0.0.1:9000;
set $my_script_name $fastcgi_script_name;
}
In this case you will have 2 scenarios:
if URI starts with /page/, Nginx will run /var/www/$main_host/www/path/to/file.php.
if URI ends with .php, Nginx will run requested php file, as usual.
Solution #3:
Leave your \.php$ location as is and put the following location before it:
location ~ ^/page/ {
include /etc/nginx/conf.d/fastcgi_params.conf;
fastcgi_param SCRIPT_FILENAME /var/www/$main_host/www/path/to/file.php;
fastcgi_param DOCUMENT_ROOT /var/www/$main_host/www;
fastcgi_param PHP_ADMIN_VALUE upload_tmp_dir=/var/www/$main_host/tmp/upload;
fastcgi_param PHP_ADMIN_VALUE session.save_path=/var/www/$main_host/tmp/sessions;
}
Just replace /path/to/file.php with real path to file which should handle such requests.
