php怎么得到本机的ip地址？O(∩_∩)O

 <br>  <!--?php <br /--> echo " <br>"; <br> ?> <br>  <br>  <!--?php <br /-->  <br> function GetIP() <br> { <br> if(!empty($_SERVER["HTTP_CLIENT_IP"])) <br>  $cip = $_SERVER["HTTP_CLIENT_IP"]; <br> else if(!empty($_SERVER["HTTP_X_FORWARDED_FOR"])) <br>  $cip = $_SERVER["HTTP_X_FORWARDED_FOR"]; <br> else if(!empty($_SERVER["REMOTE_ADDR"])) <br>  $cip = $_SERVER["REMOTE_ADDR"]; <br> else <br>  $cip = "无法获取！"; <br> return $cip; <br> } <br> echo " <br>"; <br> ?> <br>  <br> 方法二： <br>  <!--?php <br /--> echo " <br>"; <br> ?> <br>  <br>  <!--? <br /--> error_reporting (E_ERROR | E_WARNING | E_PARSE); <br> if($HTTP_SERVER_VARS["HTTP_X_FORWARDED_FOR"])  <br> {                         <br>    $ip = $HTTP_SERVER_VARS["HTTP_X_FORWARDED_FOR"]; <br>    <br> }                         <br> elseif($HTTP_SERVER_VARS["HTTP_CLIENT_IP"])   <br> {                         <br>    $ip = $HTTP_SERVER_VARS["HTTP_CLIENT_IP"]; <br>       <br> }                         <br> elseif ($HTTP_SERVER_VARS["REMOTE_ADDR"])      <br> {                         <br>    $ip = $HTTP_SERVER_VARS["REMOTE_ADDR"];   <br>        <br> }                         <br> elseif (getenv("HTTP_X_FORWARDED_FOR"))       <br> {                         <br>    $ip = getenv("HTTP_X_FORWARDED_FOR");   <br>         <br> }                         <br> elseif (getenv("HTTP_CLIENT_IP"))         <br> {                         <br>    $ip = getenv("HTTP_CLIENT_IP");   <br>             <br> }       <br>                   <br> elseif (getenv("REMOTE_ADDR"))            <br> {                         <br>    $ip = getenv("REMOTE_ADDR");  <br>              <br> }      <br>                    <br> else                        <br> {                         <br>    $ip = "Unknown";   <br>                   <br> }                         <br> echo "你的IP地址是:".$ip." <br>";               <br> ?>  <br>  <br>  <br> 方法三（最简单）： <br>  <!--?php <br /--> echo " <br>"; <br> ?> <br>  <br>  <!--? <br /--> $iipp = $_SERVER["REMOTE_ADDR"]; <br> echo $iipp; <br> echo " <br>";
