No, debug does not help here.

The rewrite module debug log is as ugly as it is itself.
Here I see that
10085#0: *741 http script copy: “”
10085#0: *741 http script copy: “”
10085#0: *741 http script var: “”

10085#0: *741 http fastcgi header: “Status: 404 Not Found”
And PHP sends 404.
Probably it tries to work with
fastcgi_param PATH_TRANSLATED $document_root$fastcgi_script_name;
or
fastcgi_param REQUEST_URI $request_uri;
Try to delete them and use
fastcgi_param SCRIPT_FILENAME $document_root$script_name;
fastcgi_param PATH_INFO $path_info;
only.
I’ve been poring over the debug logs after trying test cases. I don’t
know if I found anything interesting here, but thought I’d pass it on.
Here’s one that worked, the /galleries in root:

And here’s one that failed, the php file photos two down in a subdir.
The one major difference: It has a http script copy: "/ MSIE " before
the script capture that the working debug didn’t have…is that
anything?

Igor,
Hadn’t noticed that in the:
if ($uri ~ ^/(?:.+/)?(testgalleries|galleries|poll|news|photos)(/.*)) {
you had changed:
set $script_name $1; to set $script_name /$1;
Made that change…still no go.
Added “test” to the file list above. Tossed nothing into it except for
<?php phpinfo(); ?>Going to /subdir/subdir/test showed the phpinfo.
/subdir/subdir/test/ and /subdir/subdir/test/1 both showed nothing.
In all three cases though, the access log showed 200s, no 404s.
I’m staring at all the regexes and can’t see how we’ve got
/galleries, /galleries/, and /galleries/24/1/1 all working fine but this
new regex is working on /subdir/subdir/photos but tripping up on
/subdir/subdir/photos/ and /subdir/subdir/photos/1
Again, thanks for nginx and all the help. I’m moving fast on this
because one of the ad networks will be featuring us soon and I’d love to
be 100% nginx by then.
Just wanted to reiterate my activities tonight.
I’ve spent so much time looking at the debug logs this evening, I feel
like I’ve become one with my monitor.
In the location that Igor suggested for finding an extensionless php
file in multiple sub dirs, nginx has been able to find and run the file
at:
/subdir/subdir/test
A-OK, file runs as expected, people cheer in the streets.
I changed the test file from it’s original script to just a phpinfo();
to make sure nothing in the script could have been causing the failure.
/subdir/subdir/test gave us the phpinfo()
/subdir/subdir/test/ and /subdir/subdir/test/1 create a blank screen.
There’s a 200 OK response, the fastcgi server sends:
http fastcgi header: “X-Powered-By: PHP/5.2.5”
http fastcgi parser: 0
http fastcgi header: “Content-type: text/html” and the static location
even sends the favicon.ico over. Just no phpinfo() or any html of any
kind.
I’m perplexed.
I’ve also noticed weird things in the script capture portion of the
debug.
On /subdir/subdir/test/ <–with trailing slash, there was:
32720#0: 75364 http script regex:
"^/(?:.+/)?(testgalleries|galleries|poll|news|photos|test)(/.)"
32720#0: *75364 http script if
32720#0: *75364 http script complex value
32720#0: *75364 http script copy: “/hars” <-- what’s this?
32720#0: *75364 http script capture: “/test”
32720#0: *75364 http script set var
32720#0: *75364 http script complex value
32720#0: *75364 http script capture: “/”
32720#0: *75364 http script set var
Where did /hars come from?
On /subdir/subdir/test/1 there was:
32720#0: 76311 http script regex:
"^/(?:.+/)?(testgalleries|galleries|poll|news|photos|test)(/.)"
32720#0: *76311 http script if
32720#0: *76311 http script complex value
32720#0: *76311 http script copy: “/” sr" <-- what’s this?
32720#0: *76311 http script capture: “/test”
32720#0: *76311 http script set var
32720#0: *76311 http script complex value
32720#0: *76311 http script capture: “/1”
Where did “/” sr" come from. I’m guessing this weird extra info may be
screwing things up?
Thanks to all on the list for putting up with this long thread. I’ve
been running the extensionless php files (in any subdir) for almost a
decade with the simple Apache directive:
I didn’t realize that getting the same thing to work in nginx would be
such a mindbender, but I’m willing to stare at the monitor and try all
of Igor’s and the list’s suggestions because the speed, memory footprint
and general beauty of nginx make the journey worthwhile. Please keep
those suggestions coming. 
As I wrote to Igor earlier today, we’re 99.99% there and I’m sure we’ll
make it. I know I’m not the only one in the Apache world that’s used
extensionless php scripts so I’m sure this will finally make a wiki
entry that will encourage more folks to make the jump to nginx.
As a reminder, here’s Igor’s latest suggestion for the location:
location ~ /(testgalleries|galleries|poll|news|photos|test)(/|$) {
root /usr/local/apache/htdocs;
set $script_name $uri;
set $path_info “”;
if ($uri ~
^/(?:.+/)?(testgalleries|galleries|poll|news|photos|test)(/.*)) {
set $script_name /$1;
set $path_info $2;
fastcgi_pass 127.0.0.1:10004;
}
fastcgi_param GATEWAY_INTERFACE CGI/1.1;
fastcgi_param SERVER_SOFTWARE nginx;
fastcgi_param QUERY_STRING $query_string;
fastcgi_param REQUEST_METHOD $request_method;
fastcgi_param CONTENT_TYPE $content_type;
fastcgi_param CONTENT_LENGTH $content_length;
#fastcgi_param PATH_TRANSLATED $document_root$fastcgi_script_name;
#fastcgi_param REQUEST_URI $request_uri;
fastcgi_param DOCUMENT_URI $document_uri;
fastcgi_param DOCUMENT_ROOT $document_root;
fastcgi_param SERVER_PROTOCOL $server_protocol;
fastcgi_param REMOTE_ADDR $remote_addr;
fastcgi_param REMOTE_PORT $remote_port;
fastcgi_param SERVER_ADDR $server_addr;
fastcgi_param SERVER_PORT $server_port;
fastcgi_param SERVER_NAME $server_name;
fastcgi_param SCRIPT_FILENAME $document_root$script_name;
fastcgi_param PATH_INFO $path_info;
fastcgi_param REDIRECT_STATUS 200;
fastcgi_pass 127.0.0.1:10004;
}
I wondered briefly if:
set $script_name /$1; was a typo but changing it to $1 doesn’t fix it
either.
Thanks everyone.

Great. Scriptname is correct. Root’s correct. Path_info is empty. It works.
Now I called /academy/80/test/12
phpinfo() should come up and the only major change is that path_info should
be 12.The debug logs show that it’s passing a path_info of /12
The script filename is correct. But phpinfo() doesn’t run.

Looks like you’ve got wrong SCRIPT_FILENAME. At least - this
differs from the one in the above request.
Maxim D.
Banging my head on the desk here. I added ‘test’ to the list of
filenames that can be extensionless. Placed it a few subdirs down.
All ‘test’ contains is the phpinfo();
When I go to /academy/80/test, the phpinfo() comes up. Here are the
params from the nginx debug:

I’m perplexed. If it’s passing the correct stuff onto php, why isn’t it
running?
Thanks.
Hello!

You old regex was capturing only last path component.

I think you’ve done it! All the test cases appear to work. $PHP_SELF
seems to not work as well in the CGI environment, but I’ve read about
issues with that in the past, so that’ll be a PHP fix.
Otherwise I think I’m pretty much ready to go 100% nginx.
Thanks!
Hi Ian,
Could you post the final and complete configuration file for the php
section so we can have a global look at it? That might save days of
work for other people in the future.
Glad you could sort it out 100%.

from the one in the above request.
Thanks…that’s why a second set of eyes helps! I stared at that for a
while before posting and didn’t see it.
Looking at the location, can you see how it’s stripping the subdir(s)
out? Or how to get the subdirs back in?
Thanks!

Will do. The only thing I’m still noticing is the possible issue with
scripts that use $_SERVER[‘PHP_SELF’].
If a .php (or in my case, .shtml as well) file is called it equals the
filename e.g. _SERVER[“PHP_SELF”] = /test.php
If an extensionless file (in this case ‘test’) is called,
_SERVER[“PHP_SELF”] = no value
This is a bit of an issue for things like forms scripts or pagination
scripts that use _SERVER[“PHP_SELF”].
Obviously, I can rewrite my own stuff to not need _SERVER[“PHP_SELF”],
but for people who might look for a drop in solution or are using a
cut’n’paste script, it might be a problem.
If anyone has an idea why the extensionless files aren’t creating
_SERVER[“PHP_SELF”] or a way to create it, please let us know.
Thanks!
