PHP obtains the real IP address of the local machine example code_php skills

The example in this article shares with you the php code to obtain the real IP address of the machine for your reference.

Mainly to obtain the real IP address of the machine whose operating system is win2000/xp, win7, and to obtain the real IP address of the machine whose operating system is linux. The specific content is as follows

function getLocalIP() {
 $preg = "/\A((([0-9]?[0-9])|(1[0-9]{2})|(2[0-4][0-9])|(25[0-5]))\.){3}(([0-9]?[0-9])|(1[0-9]{2})|(2[0-4][0-9])|(25[0-5]))\Z/";
//获取操作系统为win2000/xp、win7的本机IP真实地址
 exec("ipconfig", $out, $stats);
 if (!empty($out)) {
  foreach ($out AS $row) {
   if (strstr($row, "IP") && strstr($row, ":") && !strstr($row, "IPv6")) {
    $tmpIp = explode(":", $row);
    if (preg_match($preg, trim($tmpIp[1]))) {
     return trim($tmpIp[1]);
    }
   }
  }
 }
//获取操作系统为linux类型的本机IP真实地址
 exec("ifconfig", $out, $stats);
 if (!empty($out)) {
  if (isset($out[1]) && strstr($out[1], 'addr:')) {
   $tmpArray = explode(":", $out[1]);
   $tmpIp = explode(" ", $tmpArray[1]);
   if (preg_match($preg, trim($tmpIp[0]))) {
    return trim($tmpIp[0]);
   }
  }
 }
 return '127.0.0.1';
}
