The Tips

1. Make sure you know which php.ini file is active. If you have installed PHP multiple times it's probably a good idea to remove the old installs.


2. To save time, make sure file extensions are visible:
   In Windows Explorer, select Folder Options >View tab, and make sure "Hide extensions for known file types" is not checked.

   



3. After each change to configuration files or file locations, restart IIS and the application pool.


4. If you make a change to php.ini and restart IIS and the application pool, but the setting change seems to have no effect, check that the setting is listed only ONCE in php.ini.
5. Make sure that execute permissions are set on the website:
   In IIS 7, select the website. Double-click the Handler Mappings icon.
   
   Then click Edit Feature Permissions... and check Execute
   


6. Double-check that the extension directory path listed in php.ini matches the path to your php extension directory.



; Directory in which the loadable extensions (modules) reside.

;extension_dir = "./"

extension_dir = "C:\Program Files\PHP\v5.2\ext"





7. Make sure that the PATH environment variable contains the path to the php executable.
   for example
   

   C:\Program Files\PHP\v5.2;

   or
   

   C:\PHP\;

   
   


8. Now open the php.ini file that is in the PHP folder you just installed.

   Search for and comment out doc_root if it isn't already.
   

   ; doc_root =




9. FastCGI configuration
   Install FastCGI
   Download FastCGI for IIS

   Detailed instructions on setting up FastCGI on IIS

   Make sure the extension is in the %windir%\system32\inetsrv" directory, for example:
   

   C:\WINDOWS\system32\inetsrv\fcgiext.dll

10. Set up Type associations correctly in fcgiext.ini [Learn More]

    
    Find and open C:\WINDOWS\system32\inteserv\fcgiext.ini
    The editable sections are toward the bottom of the file. Find the [TYPES] section. This section maps file extensions from the URL with FastCGI applications. Read the examples and add the mappings needed for your setup.

    Example:
    

    
    
    [Types]
    
    php:/W3SVC/364137164/Root=PHP52_via_FastCGI
    
    php=PHP52_via_FastCGI
    
    

    
    


11. Configure Environment variables in fcgiext.ini.
    Example:
    

    
    
    [PHP52_via_FastCGI]
    
    ExePath=C:\Program Files\PHP\v5.2\php-cgi.exe
    
    InstanceMaxRequests=10000
    
    ActivityTimeout=600
    
    RequestTimeout=600
    
    EnvironmentVars=PHP_FCGI_MAX_REQUESTS:10000,PHPRC:%ProgramFiles%\PHP\v5.2
