The other info you see is optional, all that is required is the portion you have listed

<Files directory>
ForceType application/x-httpd-php
#SetHandler application/x-httpd-php
#SetHandler application/x-httpd-php5
#ForceType x-httpd-php
</Files>


Lines that begin with # are commented and ignored by your server, so if
ForceType application/x-httpd-php isnt the right directive for your server, try the next by toggling the comment

<Files directory>
#ForceType application/x-httpd-php
SetHandler application/x-httpd-php
#SetHandler application/x-httpd-php5
#ForceType x-httpd-php
</Files>

Still not working ?, try the next one


<Files directory>
#ForceType application/x-httpd-php
#SetHandler application/x-httpd-php
SetHandler application/x-httpd-php5
#ForceType x-httpd-php
</Files>

Some servers may take a minute to check for changes in the .htaccess file, so it is probably best to make an edit to the .htaccess file, save it, refresh the page, wait another 30-40 seconds refresh again. If it still doesn't work, try the next directive by toggling the commented line, as shown in the examples above.

Once you see the script actually running, you might want to look into the mod rewrite rules further down in the .htaccess, but they are only optional. This FAQ entry talks more about that, and why you might want to enable them..
