popen() opens a named pipe to a program - you can read and write to it
if the program you're piping to supports that kind of interactivity
(mostly you just read the output from the command). However, in this
case, I don't think you want either popen() or fopen() (certainly not
fopen() - that just opens a file and that's not at all what you want).
You can use a system call or just backticks around the call to useradd
(if it's on the same server as your web server). If it's not, you'll
have to use sockets and or xmlrpc or some other messaging service.

BUT...you probably know that useradd requires root privs. So you either
have your webserver running  as root (a really really bad idea), or you
have it configured to allow suid programs or you have useradd as suid
root - also not really good ideas.

Maybe you want to take a look at a program called Webmin
(http://www.webmin.com/) that already does what you are talking about. I
haven't used it for several years, but as I remember, it was a pretty
handy tool.

  does that r just mean read? and if so should that r be a w for =

 If you are just checking the name/password against an existing list, then
 you only need read. If you want to add something, then you need a
 different mode.

 However, I think you may be better off uing fopen, instead of popen, if
 you are trying to do what I think you are. The documentation for
 fopen has
 a comprehensive description of the modes available; note that w is kindof
 destructive in the wrong context :-)

r+ allows you to read and write... if that's what you wanted (I think it
is).  Note that it will write over any data that is behind the location of
the file pointer (so write to the end of the file).
