Questions[phpinfo](server)

I have a php file at http://lohray.com/info1.php that is just -

<?php
    phpinfo();
?>

The page does not render on my browsers (I have tried chrome and firefox), however, wget fetches all the HTML. What might be going wrong? My apache / php are running on an EC2 instance.

Using the developer tools, I can see that I have received a 200 header with X-Powered-By:PHP/5.3.10.

I am trying to run a simple PHP script which displays phpinfo() but I am getting 500 internal server error. What could be the reason? Is it because PHP handler is set to suPHP and I shall change it to DSO or CGI?

Thanks

I have a publicly accessible page which just has

<?php phpinfo(); >

I use it for debugging purposes while we're in beta, but is there any harm in leaving it accessible when its a live site?

Does this mean that selinux is currently enabled on my system?

In /etc/sysconfig/selinux, I set:

  SELINUX=disabled

AND then rebooted the server, but still in phpinfo() the same thing is showing up!

How do I disable it permanently?

(Nothing against selinux, but I have scripts that need to execute other programs - and it appears that selinux is interfering with them... What permissions are needed to run a system() command within a php script that writes to a folder?)

Edit 1:

If it helps, I also did the same in: /etc/selinux/config

I downloaded the php-5.3.3-Win32-VC6-x86.msi file from php's download page. I have a working apache2 server running. On the setup window I selected the apache 2.2.x Module and on the Apache Configuration directory I selected the conf file.

The info.php page isn't appearing on my browser (404 Not Found), why?
