PHP and Apache 1.3.12

Hi, I am using RedHat Linux 6.2. I just got my PHP installed but my Apache 1.3.12 server does not seem to recognize the PHP files and PHP scripting. I have already uncommented the lines in my httpd.conf file which read: > AddType application/x-httpd-php .php > AddType application/x-httpd-php-source .phps when I type httpd -l, I notice the following: >[root@test bin]# ./httpd -l >Compiled-in modules: > http_core.c > mod_env.c > mod_log_config.c > mod_mime.c > mod_negotiation.c > mod_status.c > mod_include.c > mod_autoindex.c > mod_dir.c > mod_cgi.c > mod_asis.c > mod_imap.c > mod_actions.c > mod_userdir.c > mod_alias.c > mod_access.c > mod_auth.c > mod_setenvif.c > suexec: enabled; valid wrapper /usr/local/apache/bin/suexec I am not sure why my Apache still does not recognize php files. When I try to access a php file on the server through a web browser, it will ask me if I want to download. It's almost as though it did not recognize the PHP extension. I was reading through some of README files that came with the PHP source files and it mentioned that I need to have the "mod_so" active. Well as you can see "mod_so" was not on my list when I typed httpd -l. I have read the Apache documentation, but I am lost in terms of how to install this mod_so module. I was wondering has anybody out there had a similar experience. If so can anyone offer any suggestions. thanks.
