Mysql – PHP shows page source code in browser

Check that you have the Frontpage extensions enabled on the Server. For information about enabling Web service extensions, see this TechNet article: Enabling Web Service Extensions (IIS 6.0):

To enable Web service extensions

1. In IIS Manager, click the Web Service Extensions folder.
2. In the details pane, select the Web service extension that you want to enable, and then click Allow.
3. To see the properties of a Web service extension, select an extension, and then click Properties.

I recently implemented a similar setup:

• Windows Server 2003 Web Edition
• IIS / FastCGI (http://www.iis.net/expand/fastcgi)
• PHP 5.3.1 (installed via zip file into c:\php)

From my deployment notes, the install steps were:

• Download PHP 5.3.1 zip (http://windows.php.net/download/, note the "Which version do I choose?" section)
• Install into c:\php
• Test php -v works on the command line (in c:\php)
• Associate .php with FastCGI: IIS Manager -> machine -> Web Sites -> site -> right click, choose properties -> choose "Home Directory" tab, click "Configuration", Mappings tab. Config for .php looks like:

• Configure FastCGI's config file (C:\WINDOWS\system32\inetsrv\fcgiext.ini) with at least:

    [Types]
    php=PHP

    [PHP]
    ExePath=c:\php\php-cgi.exe

• Append/change the following to c:\php\php.ini. Without this config, my config bounces between giving blank pages and not loading at all (I guess this is your problem):

    fastcgi.impersonate = 1
    fastcgi.logging = 0
    cgi.fix_pathinfo=1
    cgi.force_redirect = 0

• Set

  display_errors

  on in c:\php\php.ini and uncomment extension=php_mysql.dll.
• Restart IIS for the site (click the stop/play buttons)

In this config, you've essentially got two components, the plumbing between IIS-FastCGI-PHP, and PHP itself. I'd recommend isolating which of these isn't working:

• Temporarily edit fcgiext.ini and point the PHP ExePath to something different, e.g. c:\php\nothere.exe. If the server starts returning "The FastCGI executable could not be found" for PHP requests, then I'd FastCGI was working correctly, and PHP is at fault.
• Run PHP with its default config, the fastcgi/cgi changes above and display_errors on. You'll need to restart IIS (and possibly kill off any php-cgi processes) for the site you're restarting for the changes to be recognised.
• Run PHP on the command line with a simple phpinfo(); script, to check basic operation, and note where the loaded php.ini is. This checks a rogue config file (e.g. in c:\, c:\windows etc) is not being used.

These steps confirm (at least) the PHP executable is being invoked, with the most basic config.

hope this helps,
