I wrote a simple ping user function, useful for automatically determining wether to show high
bandwidth content or calculating download times.
<?php
function PingUser() {
global $REMOTE_ADDR;
return ereg_replace(" ms","",end(explode("/",exec("ping -q -c 1
$REMOTE_ADDR"))));
}
?>
It returns a number representing the milli seconds it took to send and receive packets from the
user.
