a few things and one is this
-- and it is a SHOW STOPPER --
Code:
There was an error parsing the RHN proxy settings.
RHN support will be disabled.
this is not a paid for nor activated copy of some version of red hat
you MUST buy a license and activated your install
-- no if's and's or but's --
then you can install software .
php should be already installed from the install dvd
along with Apache and MySQL
red hat is meant for use as a server so these programs tend to be installed by default
there should be a handy desktop icon to activate it if this is the DESKTOP version

spend the $299 US for the 1 year contract
https://www.redhat.com/apps/store/desktop/
but seeing as you want the server packages
have a look at the RHEL server page
https://www.redhat.com/apps/store/server/
If you do not plan on buying it then do not use red hat
install CentOS 6.0 or ScientificLinux 6.1
https://www.centos.org/
http://www.scientificlinux.org/
they are free rebuilds of RHEL
