execute a server side program

[fizzwizz]

I would like to execute a program on my server (/home/programs/listusers) and display the output on a webpage
How can I do this?
Thanks in advance

Check out [man]system/man and [man]exec/man

echo shell_exec( '/home/programs/listusers' );

Thanks

That returns the following error that I don't understand. Can you shed some light on this for me?

Warning: Cannot execute using backquotes in safe mode in /home/virtual/site12/fst/var/www/html/test.php on line 10

You cannot execute stuff when PHP is in safemode.
