I'm mixing a configuration with userdir and symfony2 (http://wiki.nginx.org/Symfony) for a development environment, php is using php-fpm and a unix socket.
The userdir configuration is classic, all your files in `~user/public_html/` will be accessible through `http://server/~user/`.
I add to this the fact that if you create a folder `~user/public_html/symfony/` and put a symfony project in it (`~user/public_html/symfony/project/`) it will have the usual symfony configuration applied (rewrites and fastcgi path split).

Here you go for the configuration :
{{{
    # match 1:username, 2:project name, 3:the rest
    location ~ ^/~(.+?)/symfony/(.+?)/(.+)$ {
        alias /home/$1/public_html/symfony/$2/web/$3;
        if (-f $request_filename) {
            break;
        }
        # if no app.php or app_dev.php, redirect to app.php (prod)
        rewrite ^/~(.+?)/symfony(/.+?)/(.+)$ /~$1/symfony/$2/app.php/$3 last;
    }

    # match 1:username, 2:project name, 3:env (prod/dev), 4:trailing ('/' or
    # end)
    location ~ ^/~(.+?)/symfony(/.+)/(app|app_dev)\.php(/|$) {
        root /home/$1/public_html/symfony$2/web;
        # fake $request_filename
        set $req_filename /home/$1/public_html/symfony$2/web/$3.php;
        include fastcgi_params;
        fastcgi_split_path_info ^((?U).+\.php)(/?.+)$;
        fastcgi_param PATH_INFO $fastcgi_path_info;
        fastcgi_param PATH_TRANSLATED $document_root$fastcgi_path_info;
        fastcgi_param SCRIPT_FILENAME $req_filename;
        fastcgi_pass unix:/tmp/php-fpm.sock;
    }
}}}

The second block (PHP backend) works on its own. The first block (files direct access) works on its own.

You can see that I already had a problem with PHP but went around it with creating my own variable.

To help understand, here is a sample of a symfony project layout (I removed some folders to help the comprehension):
{{{
project/
    src/
        [... my php code ...]
    web/
        app_dev.php
        app.php
        favicon.ico
}}}

If I try to access `http://server/~user/symfony/project/favicon.ico` I see this in the logs :
{{{
2012/01/17 16:36:25 [error] 27736#0: *1 open() ""/home/user/public_html/symfony/project/web/favicon.icoavicon.ico"" failed (2: No such file or directory), client: 10.11.60.36, server: server, request: ""HEAD /~user/symfony/project/favicon.ico HTTP/1.1"", host: ""server""
}}}

If I remove the block that tests `$request_filename`, it works but I have to remove the rewrite as well.

The server is a CentOS 5.7 and the nginx is coming from the EPEL repository.

Unfortunately my C skills are down the floor so I can't really provide a better understanding of the problem. I tried to poke around the code but with not much luck."	defect	accepted	minor		nginx-core					Linux bjs-fl-dev-web06 2.6.18-274.12.1.el5xen #1 SMP Tue Nov 29 14:18:21 EST 2011 x86_64 x86_64 x86_64 GNU/Linux	"nginx version: nginx/0.8.55
