    Get a list of network interfaces in PHP?

    Hi All,

    I've got a utility I'm working on, and I want to be able to list for
    the user all the current network interfaces on the machine. Is there a
    way to do this in PHP? PHP 5.0.3, Mandriva Linux 2005 (2.6 kernel).
    I'm not actually in front of the machine in question, and I don't
    recall the minor kernel version, or the minor version of Mandriva...

    Any thoughts? I'd prefer not to have to run the script as root,
    incidentally. I realize I could run as root and then just parse the
    output of ifconfig, but I assume there's a more intelligent way to go
    about what I'm trying to do.

    The purpose of this utility is to allow me to issue a ping, from a
    specified interface (including virtual interfaces, e.g., eth0:1), and
    test for connectivity from the webserver to the the address i am
    pinging, through the specified network interface (rather than always
    pinging from the default/primary interface of the machine).

    Any thoughts? How would I go about this? I haven't been able to come
    up with a way to do this, short of running as root and parsing
    ifconfig, as I mentioned above.

      I would not use PHP for this. Perhaps C(++), far more up to the task.

          You can read in the /proc files. Try for example $cat /proc/net/dev.
