...unless the URI never contains .php but instead is handled by PHP interpreter
via Apache rewrite rule:
RewriteRule ^(.*)$ /index.php$1 [L]
And in this case, when accessing URL /foo/bar, both PHP_SELF and SCRIPT_NAME
are
set to "/foo/bar". This is exactly what I want to achieve in cgi/fpm SAPI in
nginx, but cannot find any way so far. Best I could come up with is not to
submit SCRIPT_NAME and submit PHP_SELF equal to $uri.

Jerome, thanks for looking into this issue.
The main trouble is that sometimes, even for FCGI/FPM SAPI both SCRIPT_NAME and
PHP_SELF must refer to the original URI, and *NOT* to SCRIPT_FILENAME! This
behaviour is desired, for example, in order to support older eZPublish or
vTiger
CRM code that relies on PHP_SELF and assumes it contains the original URI, not
the SCRIPT_FILENAME, which would be /index.php.
So, I thought it would be as simple as this:
fastcgi_param PHP_SELF $uri;
fastcgi_param SCRIPT_NAME $uri;
Apparently, it isn't, and PHP-FPM adjusts these variables by itself, even though
they are submitted via server environment. I've been experiencing situations
when PHP_SELF would contain a double path, or that PHP_SELF would contain
/index.php/, but all I need both to contain is the original URI without
arguments.
In addition, when cgi.fix_pathinfo is set to 0, I am not able to access any PHP
scripts as I get "No input file specified" response in the browser.
Please additionally notice that your suggestion with fastgi_split_path_info
doesn't work, no matter which value cgi.fix_pathinfo is set to, as
PATH_INFO/PATH_TRANSLATED remain empty.

As described in http://php.net/manual/en/reserved.variables.server.php
'PHP_SELF': The filename of the currently executing script, relative to the
document root. For instance, $_SERVER['PHP_SELF'] in a script at
the address http://example.com/test.php/foo.bar would be /test.php/foo.bar
whereas
'SCRIPT_NAME': Contains the current script's path.(without further details).
If we look into the code of differents SAPIs, here what's done:
apache2handler: PHP_SELF is set REQUEST_URI given by apache. So it should be
/test.php/foo.bar
cgi/fpm (the code for this part is the same):
PHP_SELF is set to REQUEST_URI if cgi.fix_pathinfo is 0.
PHP_SELF is set to SCRIPT_NAME if cgi.fix_pathinfo is 1.
this cgi.fix_pathinfo is a real mess (see
https://bugs.php.net/bug.php?id=51983).
I don't really know what to think about all this right now ...

I know, but if I don't set PHP_SELF to $uri, then older PHP scripts that
haven't
been written for FastCGI mode and that require that PHP_SELF refers to the URI,
as
in mod_php/apache case, won't work! So I *need* to set both SCRIPT_NAME and
PHP_SELF to $uri actually.

I tried your suggestion and it doesn't set PATH_INFO correctly:
Accessing "http://testsite.com/test/test%20test":
Array
(
[SCRIPT_FILENAME] => /opt/www/testsite.com/index.php
[REQUEST_URI] => /test/test%20test
[PATH_INFO] =>
[PATH_TRANSLATED] => /opt/www/testsite.com
[PHP_SELF] => /index.php
[SCRIPT_NAME] => /index.php
)
PATH_INFO should be set to "/test/test%20test/", i believe?

SCRIPT_NAME is already defined in the fastcgi_params file. PHP_SELF doesn't
have to be set in nginx as it's made in FPM.
Can you try the following nginx configuration please ?
location ~ ^.+\.php {
include fastcgi_params;
fastcgi_split_path_info ^(.+\.php)(.*)$;
fastcgi_param PATH_INFO $fastcgi_path_info;
fastcgi_param PATH_TRANSLATED $document_root$fastcgi_path_info;
vastcgi_param PHP_VALUE "include_path=$document_root:$document_root/include";
fastcgi_pass unix:/var/run/fastcgi/php-fpm.sock;
try_files fastcgi_script_name =404;
}
it should be exactly the same as your configuration and it sould work.
thx
