PHP 获取 ping 时间的实现方法

malike

            PHP 可以通过exec函数执行shell命令，来获取ping时间。
代码示例：
echo 'PHP_INT_MAX : ' . PHP_INT_MAX . "
";

$ip = '115.29.237.28';    // IP地址

if (PATH_SEPARATOR==':')  // linux
{
  echo 'I am linux' . "
";
   
  exec("ping -c 3 -w 5 $ip", $info);
  echo 'linux info : ' . "
";
  print_r($info);
   
  $ping_time_line = end($info);
  echo '
ping_time_line : ' . $ping_time_line . "
";
   
  $ping_time = explode("=", $ping_time_line)[1];
  $ping_time_min = explode("/", $ping_time)[0] / 1000.0;
  $ping_time_avg = explode("/", $ping_time)[1] / 1000.0;
  $ping_time_max = explode("/", $ping_time)[2] / 1000.0;
   
  echo $ping_time_min . " " . $ping_time_avg . " " . $ping_time_max . "
";
   
}
else             // windows
{
  echo 'I am windows' . "
";

  exec("ping -c 3 -w 5 $ip", $info);
  echo 'windows info : ' . "
";
  print_r($info);
   
  $info_time = end($info);
  echo '
info_time : ' . $info_time . "
";
}
