Answer 1

I just pinged google with that exec

<?php
echo exec("ping www.google.com");
?>

output was:

Packets: Sent = 4, Received = 0, Lost = 4 (100% loss),

Answer 2

$ip =   "127.0.0.1";
exec("ping -n 3 $ip", $output, $status);
print_r($output);

output looks like below

Array
(
    [0] => 
    [1] => Pinging 127.0.0.1 with 32 bytes of data:
    [2] => Reply from 127.0.0.1: bytes=32 time<1ms TTL=128
    [3] => Reply from 127.0.0.1: bytes=32 time<1ms TTL=128
    [4] => Reply from 127.0.0.1: bytes=32 time<1ms TTL=128
    [5] => 
    [6] => Ping statistics for 127.0.0.1:
    [7] =>     Packets: Sent = 3, Received = 3, Lost = 0 (0% loss),
    [8] => Approximate round trip times in milli-seconds:
    [9] =>     Minimum = 0ms, Maximum = 0ms, Average = 0ms
)

Answer 3

Try this

$host="192.168.0.104";

exec("ping -c 4 " . $host, $output, $result);

print_r($output);

if ($result == 0)

echo "Ping successful!";

else

echo "Ping unsuccessful!";

Note: This is dependant on the OS you are running. Windows will default to only 4 pings while Linux will ping forever.

To ping twice in Windows, use "ping -n 2 host"

To ping twice in Linux, use "ping -c 2 host"
