Php – IIS 7 / PHP 5.3.6 Permission denied when accessing network file

iisPHP

ServerA-> 64 Bit Windows 2008 (IIS 7 && PHP 5.3.6)

ServerB-> 32 Bit Windows 2003 (Fileserver)

I'm trying to access a \ServerB\directory1\directory2\file.abc via fopen through a site hosted on ServerA and am getting a Permission Denied error. It's the default website using the default application pool.

What I've tried giving the following accounts or groups in the AD full permissions to the directory (and file through inheritance) and it still gave the error:

manually created a IUSR_SERVERA account (it didn't previously exist)
IIS_WPG
Everyone
Network Service
Anonymous Access
Authenticated Users

The Identity for the DefaultAppPool is NetworkService and has 32 bit applications enabled.

IUSR_SERVERA has full permissions to the local php directory.

Any help is appreciated. I've temporarily solved the issue by copying the file needed locally to SERVERA's wwwroot folder, but that can't be a permanent solution at all.

Thanks

-Mike

Thanks for the ProcMon suggestion, it brought me to the answer. I didn't set up the default application correctly.

I read and re-read everything I could find, but nothing said this specificially:

If you need to access network files using PHP through IIS 7, set up an account with proper credentials in the Application Defaults for the site you're working on.

To do so, go into the IIS Manager

Select your site from the Connections pane
Click the View Applications link in the Actions pane (far right side of the screen)
Click Set Application Defaults in the Actions pane in the new screen
Choose DefaultAppPool from the Application Pool section
Enter proper credentials in the Physical Path credentials section

Know that changing the Process Model -> Identity in the Advanced Settings of the Default App Pool had no effect on allowing it to happen.

Php – How to get a file extension in PHP

People from other scripting languages always think theirs is better because they have a built-in function to do that and not PHP (I am looking at Pythonistas right now :-)).

In fact, it does exist, but few people know it. Meet pathinfo():

$ext = pathinfo($filename, PATHINFO_EXTENSION);

This is fast and built-in. pathinfo() can give you other information, such as canonical path, depending on the constant you pass to it.

Remember that if you want to be able to deal with non ASCII characters, you need to set the locale first. E.G:

setlocale(LC_ALL,'en_US.UTF-8');

Also, note this doesn't take into consideration the file content or mime-type, you only get the extension. But it's what you asked for.

Lastly, note that this works only for a file path, not a URL resources path, which is covered using PARSE_URL.

Php – Permissions problem when uploading images using PHP in IIS

Managed to fix the issue, I changed the upload tmp dir in php.ini to C:\Test and gave Test the permissions I required, I had already made this change but on further inspection upload_tmp_dir is set twice in the php.ini file. Uploaded files inherit the permissions of the temporary directory.
