关于PHP获取服务器地址的方法

//统一获取服务器IP地址代码

$the_local_ip= '';

$result= shell_exec("/sbin/ifconfig");

if (preg_match_all("/inet (\d+\.\d+\.\d+\.\d+)/", $result, $match)!== 0){

foreach ($match [0]as $k => $v) {

if ($match [1] [$k]!= "127.0.0.1") {

$the_local_ip= $match [1] [$k];

}

}

}

$serverIp= !empty($the_local_ip)? $the_local_ip: '127.0.0.1';
