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：
echo'PHP_INT_MAX:'.PHP_INT_MAX."
"; $ip='115.29.237.28';//IP地址 if(PATH_SEPARATOR==':')//linux { echo'Iamlinux'."
"; exec("ping-c3-w5$ip",$info); echo'linuxinfo:'."
"; print_r($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."".$ping_time_max."
"; } else//windows { echo'Iamwindows'."
"; exec("ping-c3-w5$ip",$info); echo'windowsinfo:'."
"; print_r($info); $info_time=end($info); echo'
info_time:'.$info_time."
"; }
运行结果：
PHP_INT_MAX:9223372036854775807
Iamlinux
linuxinfo:

获取Ping时间封装成函数
functionping_time($ip){
$ping_cmd="ping-c3-w5".$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)
