PHP 获取 ping 时间的实现方法

PHP 可以通过exec函数执行shell命令，来获取ping时间。

代码示例：

rush:PHP;"> 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 . "

";
}

运行结果：

rush:PHP;"> PHP_INT_MAX : 9223372036854775807

I am linux

linux info :

获取Ping时间封装成函数

rush:PHP;"> function ping_time($ip) { $ping_cmd = "ping -c 3 -w 5 " . $ip; exec($ping_cmd,$info); $ping_time_line = end($info);

$ping_time = explode("=",$ping_time)[2] / 1000.0;

$result = array();
$result['ping_min'] = $ping_time_min;
$result['ping_avg'] = $ping_time_avg;
$result['ping_max'] = $ping_time_max;

print_r($result);
}

ping_time('115.29.237.28');

运行结果：

0.025497 [ping_avg] => 0.025947 [ping_max] => 0.026753 )
