Htaccess query regarding: application/x-httpd-php

My server has been upgraded and it's now running on php 4.x and php 5.x

I use to have the following in my HTACCESS file :

AddType application/x-httpd-php .php .htm .html

Code (markup):

Now I have to use:

AddType application/x-httpd-php4 .php .htm .html

Code (markup):

But can also use:

<FilesMatch .html>
SetHandler application/x-httpd-php5
</FilesMatch>

Code (markup):

For each file like .htm do I have to do the same code as above or other?

Also is this the best way to phase html as php in htaccess or other?

Thanks Ian

 

Placing "AddType application/x-httpd-php4 .php .htm .html" in your top level htaccess file will do it well. But, it is not the best way of course because each html file will needlessly be parsed by php increasing cpu load. Best is to either use the default .php extension for all php files or something else like .phtml rather than .html or .htm.
