这篇文章主要介绍了PHP 获取 ping 时间的实现方法的相关资料,希望通过本文能帮助到大家,让大家实现这样的功能,需要的朋友可以参考下
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 . "<br><br>";
- $ip = '115.29.237.28'; // IP地址
- if (PATH_SEPARATOR==':') // linux
- {
- echo 'I am linux' . "<br><br>";
- exec("ping -c 3 -w 5 $ip", $info);
- echo 'linux info : ' . "<br>";
- print_r($info);
- $ping_time_line = end($info);
- echo '<br><br>ping_time_line : ' . $ping_time_line . "<br><br>";
- $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 . "<br><br>";
- }
- else // windows
- {
- echo 'I am windows' . "<br><br>";
- exec("ping -c 3 -w 5 $ip", $info);
- echo 'windows info : ' . "<br>";
- print_r($info);
- $info_time = end($info);
- echo '<br><br>info_time : ' . $info_time . "<br><br>";
- }
运行结果:
PHP_INT_MAX : 9223372036854775807
I am linux
linux info :
Array ( [0] => PING 115.29.237.28 (115.29.237.28) 56(84) bytes of data. [1] => 64 bytes from 115.29.237.28: icmp_seq=1 ttl=52 time=26.1 ms [2] => 64 bytes from 115.29.237.28: icmp_seq=2 ttl=52 time=27.5 ms [3] => 64 bytes from 115.29.237.28: icmp_seq=3 ttl=52 time=25.2 ms [4] => [5] => — 115.29.237.28 ping statistics — [6] => 3 packets transmitted, 3 received, 0% packet loss, time 2002ms [7] => rtt min/avg/max/mdev = 25.280/26.339/27.590/0.970 ms )
ping_time_line : rtt min/avg/max/mdev = 25.280/26.339/27.590/0.970 ms
0.02528 0.026339 0.02759
获取Ping时间封装成函数
- function ping_time($ip) {
- $ping_cmd = "ping -c 3 -w 5 " . $ip;
- exec($ping_cmd, $info);
- $ping_time_line = end($info);
- $ping_time = explode("=", $ping_time_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;
- $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:Array ( [ping_min] => 0.025497 [ping_avg] => 0.025947 [ping_max] => 0.026753 )
