I want to do as the title states. To ping a users IP and return a result in ms, for instance:
Ping IP return 400ms.
I have no idea how to do this but I expe
Try this:
<?php
$ip = $_SERVER['SERVER_ADDR']; // Get the IP address of the visitor
$result = system('ping -n 1 '.$ip, $retval); // the result contains the last line of the ping command.
if ($retval==0) echo "OK";
if ($retval==1) echo "NOT OK";
?>
try this
<?php
$out = array();
exec('ping -c 4 '.$_SERVER['REMOTE_ADDR'], $out);
print_r($out);
?>
