look in your httpd.conf file. There should be three different lines:
LoadModule php4_module libexec/libphp4.so
AddModule mod_php4.c
AddType application/x-httpd-php .php .php3 .html .htm
Make sure they are not commented out, and restart apache.
For the apachectl status to work, you need to uncomment out the section that looks like this:
#<Location /server-status>
SetHandler server-status
Order deny,allow
Deny from all
Allow from .your_domain.com
#</Location>
And restart apache and you're done.
