I have been struggling with this for more than 5 hours now, and I can't seem to find the fix to my problem.
Basically, I set up virtual host on my Fedora Core server (on custom port 55555).
Any time I try to access php files by typing in browser for example 111.111.111.111:55555/somefile.php browser forces this file to download.
I want php files to be parsed.

The following is my httpd.conf appended part:

Listen 55555

<VirtualHost *:55555>
 DocumentRoot "/var/www/vhosts/example.com/httpdocs/app/"
 ServerName 111.111.111.111:55555
 CustomLog "/var/log/app/access.log" combined
 ErrorLog "/var/log/app/error.log"

 <Directory "/var/www/vhosts/example.com/httpdocs/app/">
 Options Indexes MultiViews FollowSymLinks
 AllowOverride All
 Order allow,deny
 Allow from all
 </Directory> 
</VirtualHost>

Anyone has clue why the php files are forced to download and how to parse them?

Well, the point is that when I set up domain under plesk php files are parsed without any problem.

In httpd.conf there are only 3 lines referring to php configuration:

DirectoryIndex at_domains_index.html index.html index.html.var index.shtml index.cfm index.php index.htm index

AddType application/x-httpd-php .php
AddType application/x-httpd-php-source .phps

In conf.d folder in php.conf file I have the following content:

#
# PHP is an HTML-embedded scripting language which attempts to make it
# easy for developers to write dynamically generated webpages.
#

LoadModule php5_module modules/libphp5.so

#
# Cause the PHP interpreter to handle files with a .php extension.
#
AddHandler php5-script .php
AddType text/html .php

#
# Add index.php to the list of files that will be served as directory
# indexes.
#
DirectoryIndex index.php

#
# Uncomment the following line to allow PHP to pretty-print .phps
# files as PHP source code:
#
#AddType application/x-httpd-php-source .phps

Fix the problem by enabling php modules. Here is how my Virtual Host configuration looks like:

Listen 55555

<VirtualHost *:55555>
 DocumentRoot "/var/www/vhosts/example.com/httpdocs/app/"
 ServerName 111.111.111.111:55555
 CustomLog "/var/log/app/access.log" combined
 ErrorLog "/var/log/app/error.log"

 <Directory "/var/www/vhosts/example.com/httpdocs/app/">
 Options Indexes MultiViews FollowSymLinks
 AllowOverride All
 Order allow,deny
 Allow from all
 </Directory>

 <Directory /var/www/vhosts/example.com/httpdocs/app>
 <IfModule sapi_apache2.c>
 php_admin_flag engine on
 php_admin_flag safe_mode on
 php_admin_value open_basedir "/var/www/vhosts/example.com/httpdocs/app:/tmp"
 </IfModule>
 <IfModule mod_php5.c>
 php_admin_flag engine on
 php_admin_flag safe_mode on
 php_admin_value open_basedir "/var/www/vhosts/example.com/httpdocs/app:/tmp"
 </IfModule>
 </Directory> 
</VirtualHost>
