can't get php to work with apache

I am running RedHat Linux 7.2 with PHP/4.0.6
from the shell I can use php fine. but when browsing to a php file I get a blank screen.
Does anyone have any ideas??

attached is my httpd.conf file

Thank you...for any help I can get

Did you add this (below) in your httpd.conf?


AddType application/x-httpd-php .php .php3 .php4 .phtml

Is this what your talking about?

here is a snip from my /etc/httpd/conf/httpd.conf file :

# AddType allows you to tweak mime.types without actually editing it, or to
# make certain files to be certain types.
#
# For example, the PHP 3.x module (not part of the Apache distribution - see
# http://www.php.net) will typically use:
#
<IfModule mod_php3.c>
AddType application/x-httpd-php3 .php3
AddType application/x-httpd-php3-source .phps
</IfModule>
#
# And for PHP 4.x, use:
#
<IfModule mod_php4.c>
AddType application/x-httpd-php .php .php4 .php3 .phtml
AddType application/x-httpd-php-source .phps
</IfModule>

#
# For PHP/FI (PHP2), use:
#
<IfModule mod_php.c>
AddType application/x-httpd-php .phtml
</IfModule>

If php3 + php4 coexists, don't put .php3 to:

AddType application/x-httpd-php .php .php4 .php3 .phtml
....

The IfModule directive is the worst directive ever used in Apache. It assumes everything to be true at all time. However, it's a safe way to make sure Apache startup properly when certain module is malfunctioning.
That said, to make sure mod_php4 really compiled to Apache statically or dynamically, remove or uncomment the <IfModule> and </IfModule> line. Upon startup, you can tell whether or not mod_php4 is complied properly.

I had to add the follow lines :

Action application/x-httpd-php3 /usr/bin/php
Action application/x-httpd-php /usr/bin/php

as well as taking your advice and it's working great.

thank you again...
