Description: Cannot use PATH_INFO fully with php isapi
Hi,
Due to some problems we have had with the isapi version of php under IIS,
we have made some changes in the sourcecode of this isapi module to support
Apache style PATH_INFO and PATH_TRANSLATED variables. We tested it with
IIS 5 on Windows 2000 Server.
(See also Bug number 7782).
What we have done:
- In the function "init_request_info" we have added some code which will
translate the "path_translated" server variable to a path
which points to the requested script on disk.
- In the function "sapi_isapi_register_server_variables2" we have added
some translations for the variables $PATH_INFO and $PATH_TRANSLATED
PATH_INFO will now be translated from:
/script/path/script.php/some/non/existing/path
to
/some/non/existing/path
PATH_TRANSLATED will be translated from:
d:\Inetpub\wwwroot\script.php\some\non\existing\path
to
d:\Inetpub\wwwroot\script.php
- We have added a function named "sapi_isapi_get_server_var"
which will retrieve the requested server variable and returns
a pointer to it. This function has been added to make things more
structured (because of the need to check for a "INSUFFICIENT BUFFER"
error).
We have made a patch file of these changes against the cvs version 1.7 of
php4isapi.c. This path file is attached to this e-mail.
Please keep in mind that we did not have the opportunity to test this fix with Zeus.
We hope you can/will commit this fix to the php cvs repository.
With kind regards,
Gijsbert te Riet,
Muze.

After some research ive found that iis doesnt infact support this (dont know why its
in CGI specs) You might want to take a look at:
http://support.microsoft.com/support/kb/articles/Q184/3/20.ASP
and
http://support.microsoft.com/support/kb/articles/Q252/3/52.ASP
Changing to feature/change reqest.

Verified under win2k IIS, will look into it further although this might be a general
difference between IIS and Apache PHP has no control over.

Under Apache it is possible to add non existant paths/files after a call to a script,
e.g.:
http://host/script.php/a/path/template.html
in which case Apache will start php with script.php and /a/path/template.html in the
server variable PATH_INFO.
when trying this in IIS 5.0 under windows 2000, it seems that IIS correctly calls the
phpisapi.dll, but php then returns the message:
Warning: Failed opening 'd:inetpubwwwroottest.phpapathtemplate.html' for inclusion
(include_path='') in Unknown on line 0
It would be nice if this worked like with the apache version...
