php 获取客户端的电脑名称

PHP在局域网中获取客户端计算机名、IP地址

mac测试过 可能无效

本文所述php实例可以完成获取局域网所有用户的电脑IP和主机名、及mac地址的功能，对于php程序设计人员有一定的参考借鉴价值。完整代码如下：

<?php

$bIp = gethostbyname($_ENV['COMPUTERNAME'])//获取本机的局域网IP

echo "本机IP：",$bIp,"\n"

echo "本机主机名：",gethostbyaddr($bIp),"\n\n\n"//gethostbyaddr 函数可以根据局域网IP获取主机名

//默认网关IP

list($ipd1,$ipd2,$ipd3) = explode('.',$bIp)

$mask = $ipd1 . "." . $ipd2 . "." . $ipd3

exec('arp -a',$aIp)//获取局域网中的其他IP

foreach( $aIp as $ipv) {

if(strpos($ipv,'接口') !== false) {//一下显示的IP是否是当前局域网中的 而不是其他的类型 可以在cmd下试一下命令

$bool = false

preg_match('/(?:(?:25[0-5]|2[0-4]\d|((1\d{2})|([1-9]?\d)))\.){3}(?:25[0-5]|2[0-4]\d|((1\d{2})|([1-9]?\d)))/',$ipv,$arr)

if(strcmp($arr[0],$bIp) == 0) {

$bool = true

}

} else {

if($bool) {

$str = preg_replace('/\s+/', '|', $ipv)

$sArr = explode('|',$str)

if($sArr[1] == 'Internet' || empty($sArr[1])) {

continue

}

//去除默认网关

if(strcmp($mask . ".1", $sArr[1]) == 0) {

continue

}

//去除同网关下255的IP

if(strcmp($mask . ".255", $sArr[1]) == 0) {

continue

}

//去除组播IP

list($cIp) = explode('.', $sArr[1])

if($cIp >= 224 &&$cIp <= 239) {

continue

}

echo "IP地址：|",$sArr[1],"|\n"

echo "MAC地址：",$sArr[2],"\n"

echo "主机名：",gethostbyaddr($sArr[1]),"\n"

echo "\n\n"

}

}

}
