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
++ jerome

Description:
------------
I am running nginx 1.0.4 with php-fpm and php 5.3.6.
It seems that PHP_SELF has strong dependency on the setting of SCRIPT_NAME.
When setting SCRIPT_NAME to something, $_SERVER['PHP_SELF'] will contain
PHP_SELF environment value concatenated with environment value of SCRIPT_NAME.
If SCRIPT_NAME is not set to anything, then $_SERVER['PHP_SELF'] contains what
is passed to the environment, however, since SCRIPT_NAME is not set, PHP
scripts
that rely on SCRIPT_NAME will not work.
Example #1:
accessing URL: /index.php/some/url
setting server variables:
SCRIPT_NAME /some/url
PHP_SELF /some/url
result:
print $_SERVER['SCRIPT_NAME']; // outputs: "/some/url" - OK
print $_SERVER['PHP_SELF']; // outputs: "/some/url//some/url" - NOT OK!
Example #2:
SCRIPT_NAME (unset)
PHP_SELF /some/url
result:
print $_SERVER['SCRIPT_NAME']; // outputs: ""
print $_SERVER['PHP_SELF']; // outputs: "/some/url"
Example #3:
SCRIPT_NAME /some/url
PHP_SELF (unset)
result:
print $_SERVER['SCRIPT_NAME']; // outputs: "/some/url"
print $_SERVER['PHP_SELF']; // outputs: ""
---
Bottom line: if configured as demonstrated in the first example, scripts that
rely on SCRIPT_NAME will work properly, but scripts that require PHP_SELF won't
work, as it contains the invalid URL; if configured as shown in the second
example, scripts that rely on PHP_SELF work properly, but scripts that require
SCRIPT_NAME, don't work at all; lastly, if configured as in the third example,
scripts that use SCRIPT_NAME will work properly, but scripts that use PHP_SELF
won't work, as PHP_SELF is empty.
Any workaround for this issue?
When using mod_php with apache, both SCRIPT_NAME and PHP_SELF can be set to the
same value, and will be interpreted by PHP exactly like they are passed.
However, in FCGI/PHP-FPM environment I cannot find a way to set them both to
the
same value!
How is $_SERVER['PHP_SELF'] being constructed?
Why should it rely on SCRIPT_NAME at all?
How to set server environment correctly, so it is the same under FastCGI and
under mod_php / apache 2.2?
Andrejs
Test script:
---------------
<?php
print '<pre>';
printf("SCRIPT_NAME: \"%s\"\n", $_SERVER['SCRIPT_NAME']);
printf("PHP_SELF: \"%s\"\n", $_SERVER['PHP_SELF']);
print '</pre>';
?>
Expected result:
----------------
I'd thought PHP_SELF should be possible to define explicitly through the server
environment, without other variables affecting it's value. How come is it so
that
in the apache/mod_php mode both SCRIPT_NAME and PHP_SELF contain the same
value?
This does not seem to be possible in the FastCGI environment, at least when
using
php-fpm.
