How do you ping an ip addresses in php. and give the the results as if you are on cmd program in windows

你如何在 php.ini 中 ping 一个 IP 地址？并给出结果，就像你在 windows 中的 cmd 程序一样

<?php

  system(‘ping -c 192.168.0.104'); // Ping IP address.<br>

   echo “pinged”;<br>

?>

Try this

尝试这个

$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.

注意：这取决于您运行的操作系统。Windows 将默认为只有 4 个 ping，而 Linux 将永远 ping。

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

要在 Windows 中 ping 两次，请使用“ping -n 2 host”

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

要在 Linux 中 ping 两次，请使用“ping -c 2 host”

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

output looks like below

输出如下所示

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
)
