phtml question

[Dieter Schicker]

Hi,

I have to install a php-based application on a server. Most files have
the extension *.phtml. Now my problem is that apache2 doesn't execute
them but delivers the files to the browser "as is", so that a download
dialog pops up.
=> Question: How can I get apache2 to execute those files?

Of course I have installed libapache2-mod-php4 and enabled it in the
apache configuration.

Any ideas?

Thanks in advance
Dieter
