php - 如何在php中ping ip地址并给出结果

Question

可能重复：
使用 PHP ping IP 地址并回显结果

你如何在php中ping一个IP地址。并给出结果，就好像你在 windows 中的 cmd 程序上一样

<?php

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

   echo “pinged”;<br>

?>

Answer 1

试试这个

$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!";

注意：这取决于您正在运行的操作系统。Windows 将默认只有 4 次 ping，而 Linux 将永远 ping。

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

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

Answer 2

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

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
)

Answer 3

我刚刚和那个执行官ping 了谷歌

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

输出是：

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