Hi All,

How can i implement PING command in PHP so that a visitor to my site can ping to different sites and see the response time.

Hi,

you could check out fsockopen, if it returns a handle the host is online.

$fp = fsockopen($host, $port, &$errno, &$errstr, $timeout);
if (!$fp){
echo("failed");
}
else{
echo("succeeded");
}
fclose($fp);

If you need to bypass a proxy server then $host should be your proxy server and then you send a get request to the proxy using fputs.

use the passthru() or exec() function to call the ping utility within a php page.
