Need help configuring this location directive

Server NGINX
1

I’ve been reading about how nginx matches requests - most specific to
least, then regex in the order they are listed. For fastcgi, though, all
of the tutorials suggest something like:

location ~ .php$ {
try_files $uri =404;
include fastcgi_params;
fastcgi_param SCRIPT_FILENAME
$document_root$fastcgi_script_name;
fastcgi_pass yada yada;
}

What if I want/need to run fastcgi from a location that nginx matches
before this regex, though? Do I have to repeat the whole fastcgi config
in that block, or is there a more elegant way?

For example:

root /srv/http/example.com
location = /favicon.ico {
    log_not_found off;
    access_log off;
}
# /~user/private w/basic auth
location ~ ^/~(.+?)/private(/.*)?$ {
    auth_basic "Restricted";
    auth_basic_user_file htpasswd;
    alias /home/$1/private_html$2;
    index  index.html index.htm;
    autoindex on;
}
# /~user
location ~ ^/~(.+?)(/.*)?$ {
    alias /home/$1/public_html$2;
    index  index.html index.htm;
    autoindex on;
}
# serve static files directly
location ~* ^.+.(jpg|jpeg|gif|css|png|js|ico|html|xml|txt)$ {
    access_log        off;
    expires           30d;
}
# I have no idea what this does
location ~ \..*/.*\.php$ {
    return 403;
}

fastcgi

location ~ \.php$ {
    try_files $uri =404;
    fastcgi_split_path_info ^(.+\.php)(/.+)$;
    #NOTE: You should have "cgi.fix_pathinfo = 0;" in php.ini
    include fastcgi_params;
    fastcgi_param SCRIPT_FILENAME

$document_root$fastcgi_script_name;
fastcgi_pass phpcgi;
}

So in the above example, what if I want to serve php from ~/user ?
