Check and add parameters if needed into httpd.conf:

    # Make sure there's only **1** line for each of these 2 directives:
    # Use for PHP 4.x:
    #LoadModule php4_module	modules/libphp4.so
    #AddHandler php-script	.php

    # Use for PHP 5.x:
    LoadModule php5_module	modules/libphp5.so
    AddHandler php5-script	.php 

    # Add index.php to your DirectoryIndex line:
    DirectoryIndex index.html index.php

    AddType text/html	.php

    # PHP Syntax Coloring
    # (optional but useful for reading PHP source for debugging):
    AddType application/x-httpd-php-source phps

Note 1: The php documentation recommends AddType application/x-httpd-php php instead of the above. However, it causes problems with the “MultiViews” feature of HTTP. That is, if the .php extension is left off a URL, and with certain browser Accept headers, Apache will not know .php (application/x-httpd-php) is HTML and will return a 406 Not Acceptable error. Using the AddType and AddHandler as shown above fixes this problem.
