Hi all, I am reading this guide:- http://www.iis.net/learn/application-frameworks/install-and-configure-php-applications-on-iis/using-fastcgi-to-host-php-applications-on-iis and install PHP Version 5.3.17 (windows installer) on a Windows Server 2008 R2. I am new to php and I'm not understand what does that mean to the following:- Question 1: May I know is above open_basedir is point to IIS root? open_basedir = C:\inetpub\wwwroot - Is this correct? Or it need to point to C:\php? Question 2: I am currently install 5.3.17 (Windows Installer), I know PHP extension is at C:\PHP\ext, May I know ; Directory in which the loadable extensions (modules) reside. ; http://php.net/extension-dir ; extension_dir = "./" ; On windows: extension_dir = "C:\php\ext" -- Is this correct? or "/.ext" Question 3: I totally don't see FastCgiModule in http://localhost/phpinfo.php and I don't see applicationHost.config as well NOTE: If you do not see FastCgiModule in the Modules: list, the module is either not registered or not enabled. To check if the FastCGI module is registered, open the IIS configuration file that is located at %windir%\windows\system32\config\applicationHost.config and check that the following line is present in the section: In the same file, also check that the FastCGI module is added to the section: Any idea? Please share. Thanks.
