pb with conf/apache-mime.types?

Hello,

When i test my new install (Apache+php) with the famous script
hello.html, i have a blank screen. I edit tne httpd.conf file and
verify the presence of this line :

<IfDefine HAVE_PHP4>
LoadModule php4_module extramodules/libphp4.so
</IfDefine>
<IfDefine HAVE_PHP4>
AddModule mod_php4.c
</IfDefine>
#AddType application/x-httpd-php .phpInclude conf/addon-modules/php.conf
AddType application/x-httpd-php .php .html .htm
Include conf/addon-modules/php.conf

So, i think the dynamic PHP module was enabled, and i start apache
with the option -D HAVE_PHP4.
But i have always a blank screen. I don't understand.

In my conf/apache-mime.types file, i don't have the line :
application/x-httpd-php php html htm

But the line :
application/x-php php php3 php4

It is just for interpreted php script with the mozilla browser??

My installation : Mandrake 9.1, apache-1.3.27-8mdk,
apache-conf-2.0.44-11mdk,
apache-modules-1.3.27-8mdk,
apache2-common-2.0.45-4.3mdk,
apache-suexec-1.3.27-4mdk,
libphp_common430-430-11mdk,
mod_php-4.3.1-1mdk,
php-ini-4.3.0-1mdk.

Thank for your help.

Benoit.
