It is really not a good idea to run your CGI scripts as root. If someone comprosmises your web server they have won instant access to everything. If someone finds a bug in your program they can exploit it for root access. If your program misbehaves, it can damage anything. There's a reason most things don't run as root, and a reason webservers in particular get very little access to anything -- anyone in the world can cause a request to happen, and can inject any data they want with ease.

You could perhaps use sudo to allow your webserver to run very specific things as root, so you could do system("sudo /path/to/script.sh"); Don't give it a blank cheque. Only let it run very specific scripts, and write those scripts very carefully.

NSAPI_VIRTUAL(3)							 1							  NSAPI_VIRTUAL(3)

nsapi_virtual - Perform an NSAPI sub-request

SYNOPSIS
bool nsapi_virtual (string $uri) DESCRIPTION
nsapi_virtual(3) is an NSAPI-specific function which is equivalent to <!--#include virtual...--> in SSI ( .shtml files). It does an NSAPI sub-request. It is useful for including CGI scripts or .shtml files, or anything else that you'd parse through webserver. To run the sub-request, all buffers are terminated and flushed to the browser, pending headers are sent too. You cannot make recursive requests with this function to other PHP scripts. If you want to include PHP scripts, use include(3) or require(3). Note This function depends on a undocumented feature of the Netscape/iPlanet/Sun webservers. Use phpinfo(3) to determine if it is avail- able. In the Unix environment it should always work, in Windows it depends on the name of a ns-httpdXX.dll file. Read the note about subrequests in the NSAPI section (UNIX, Windows) if you experience this problem. PARAMETERS
o $uri - The URI of the script. RETURN VALUES
Returns TRUE on success or FALSE on failure. PHP Documentation Group NSAPI_VIRTUAL(3)
