I'm trying to accomplish a nginx Configuration wich allows me based on part of the URL/ServerName to choose the project folder (document_root), all dynamic.

So if i got a Web-Server directory like:

/var/www/projecta
/var/www/project-b
/var/www/projectc

And i got the following URL matches:

www.something.projecta.demo.com -> /var/www/projecta/
xyz.project-b.demo.com -> /var/www/projectb/
aaa.bbb.ccc.ddd.projectc.demo.com -> /var/www/projectc/

and so on.

If tried it with the following configuration and it works with static files but not with PHP. As far as i can see and tell the path_info is always empty.

upstream php-www {
  server unix:/dev/shm/php-www.socket;
}

server {
  listen *:80;
  server_name  ~^(?<subdomain>.+)(?<project>[^.]+).demo.com;
  root /var/www/$project/htdocs/;

  index index.php;

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

  location ~ [^/]\.php(/|$) {
      include fastcgi_params;

      #Save path_info before it gets killed
      set $path_info $fastcgi_path_info;
      fastcgi_param PATH_INFO $path_info;
      fastcgi_param SCRIPT_FILENAME  $document_root$fastcgi_script_name;

      fastcgi_ignore_client_abort off;
      fastcgi_pass php-www;
      fastcgi_index index.php;

      fastcgi_split_path_info ^(.+?\.php)(/.*)$;

      try_files $fastcgi_script_name $uri /index.php?$query_string;
  }
}

With static files and not php-location it seems working great. the index.php actually only contains only a phpinfo();

The error message i'm getting is:

[error] 7763#7763: *3 rewrite or internal redirection cycle while internally redirecting to "/index.php", client: 192.168.2.100, server: ~^(?<subdomain>.+)(?<project>[^.]+).demo.com, request: "GET / HTTP/1.1", host: "www.foo.bar.demo.com"

Any Ideas?

The error message is a redirection loop on /index.php which probably points to the last try_files statement. Obviously $fastcgi_script_name is invalid until after fastcgi_split_path_info has processed the URI. Notice that the official nginx recipe avoids using try_files and uses an if block instead.

I would suggest that you try:

location ~ [^/]\.php(/|$) {
    fastcgi_split_path_info ^(.+?\.php)(/.*)$;
    if (!-f $document_root$fastcgi_script_name) {
        rewrite ^ /index.php last;
    }

    fastcgi_pass php-www;
    fastcgi_index index.php;

    include fastcgi_params;
    fastcgi_param PATH_INFO $fastcgi_path_info;
    fastcgi_param SCRIPT_FILENAME  $document_root$fastcgi_script_name;

    fastcgi_ignore_client_abort off;
}

Of course, if /index.php really does not exist, then you will still get a redirection loop.
