htaccess to make html act as php suffixed files

Question

To get html pages to use php scripts, I've used:

RewriteEngine on
# handler for phpsuexec. -- this makes these prefixes considered for php

SetHandler application/x-httpd-php

In a .htaccess file.
However, it works on one site, but not on another -- any ideas as to why?

Answer 1

At a rough guess there's an AllowOverride line in the main Apache config that's restricting what you can do in the .htaccess file.
