HomeBackend DevelopmentPHP Tutorialphp实现获取局域网所有用户的电脑IP和主机名、及mac地址完整实例_PHP

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:

<&#63;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
 $bool = false;
 preg_match('/(&#63;:(&#63;:25[0-5]|2[0-4]\d|((1\d{2})|([1-9]&#63;\d)))\.){3}(&#63;:25[0-5]|2[0-4]\d|((1\d{2})|([1-9]&#63;\d)))/',$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";
 }
 }
}

该程序是在cli模式下运行的,在浏览器上应该也可以
php获取局域网中的用户ip功能就完成了,主要用到的是php的exec函数 和window的arp -a  命令
其中获取本机IP:gethostbyname($_ENV['COMPUTERNAME']) 有别于以往的写法,感兴趣的朋友可以继续深入研究一下。
获取主机名函数:gethostbyaddr(IPd) 这个函数功能也很强大。

Dependency Injection in PHP: Code Examples for BeginnersDependency Injection in PHP: Code Examples for BeginnersMay 14, 2025 am 12:08 AM

You should care about DependencyInjection(DI) because it makes your code clearer and easier to maintain. 1) DI makes it more modular by decoupling classes, 2) improves the convenience of testing and code flexibility, 3) Use DI containers to manage complex dependencies, but pay attention to performance impact and circular dependencies, 4) The best practice is to rely on abstract interfaces to achieve loose coupling.

Select DependencyInjection (DI) for large applications, ServiceLocator is suitable for small projects or prototypes. 1) DI improves the testability and modularity of the code through constructor injection. 2) ServiceLocator obtains services through center registration, which is convenient but may lead to an increase in code coupling.
