nginx. Processing css files with php interpreter

Question

css

Please help with writing a regular expression in location for nginx.
There was a need to process css files from a certain directory by the php interpreter. (example: styles.css?423421423e3).
In .htaccess I wrote:

<Files styles.css>
  ForceType application/x-httpd-php
  AddHandler application/x-httpd-php .css
</Files>

but nginx gives css files bypassing apache.
In the nginx config I found the location:

location ~* ^.+\.(jpg|jpeg|gif|png|svg|js|css|mp3|ogg|mpe?g|avi|zip|gz|bz2?|rar|swf)$ {
root /var/www/myuser/data/www/site.ru;
access_log /var/www/httpd-logs/site.ru.access.log ;
access_log /var/www/nginx-logs/myuser isp;
}

and removed css from it| - everything worked.
But, now _all css files are processed by the php interpreter. How to make the php interpreter process css files only from a certain directory (and its subdirectories), and in other cases, these files would be given through nginx, as before?

Answer 1

Firstly, it is not clear now, the regular expression for file types is included in some kind of location or is registered at the top level under server.
I would write like this

location '/assets/' {
    location '/assets/do-not-serve-css' {
        location ~* ^.+\.(jpg|jpeg|gif|png|svg|js|mp3|ogg|mpe?g|avi|zip|gz|bz2?|rar|swf)$ {
           root /var/www/myuser/data/www/site.ru;
           access_log /var/www/httpd-logs/site.ru.access.log ;
           access_log /var/www/nginx-logs/myuser isp;
        }
    }
    location '/assets/feel-free-to-serve-css' {
        location ~* ^.+\.(jpg|jpeg|gif|png|svg|js|css|mp3|ogg|mpe?g|avi|zip|gz|bz2?|rar|swf)$ {
           root /var/www/myuser/data/www/site.ru;
           access_log /var/www/httpd-logs/site.ru.access.log ;
           access_log /var/www/nginx-logs/myuser isp;
        }
    }
}

Igor Sysoev, an nginx developer, recommends using this mechanism for isolating regexp locations.
According to my config, if you request a css-file at /assets/do-not-serve-css/any.css, then it will not be served through nginx and you will have to forward the processing of such a file somewhere further. If at /assets/feel-free-to-serve-css/any.css, then it will be given to nginx

Return the location css as it was, and write a new location for your directory.

location ~* ^\/path\/to\/folder\/(.+)\.css$ {
