 New Comment:

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

Hi Jerome,

I hope the information is now sufficient:

### nginx.conf:

Hi,

I'm not able to reproduce the problem on my side. Can you please provide the 
following information:

1- nginx configuration (I need the doc_root and the fastcgi and location 
configuration):
  * server {
  *   ...
  *   root ...;
  *   ...
  *   location ~ \.php {
  *     fastcgi_pass 127.0.0.1:9000;
  *     fastcgi_split_path_info ^(.+\.php)(.*)$;
  *     fastcgi_param PATH_INFO $fastcgi_path_info;
  *     fastcgi_param PATH_TRANSLATED $document_root$fastcgi_path_info;
  *     include fastcgi.conf;
  *   }
  * }

2- PHP-FPM [pool] configuration
3- ini settings cgi.fix_pathinfo

Thx
