I have another question regarding running a system command on a web server. Let me explain again, I am creating a login page that is to be used on my local lan only. I am wanting to lock down a maximum number of logins to up to 2 MAC addresses. I finally got the arp command working, but now I have another issue with new lines. The command I am running is system("arp " . $_SERVER['REMOTE_ADDR'] . " | grep " . $_SERVER['REMOTE_ADDR'] . " | cut -b34-50"); The command runs correctly, however the output is directly and not by using echo. I would like to be able to assign what is returned to a variable so that I can do additional work on it. Any ideas?
RTFM. system() is just like the C version of the function in that it executes the given command and outputs the result. Use exec: exec() executes the given command, however it does not output anything. It simply returns the last line from the result of the command. -- Postgresql & php tutorials http://www.designmagick.com/
