php获取访问者IP地址汇总

在很我的时候我们需要得到用户的真实IP地址,例如,日志记录,地理定位,将用户信息,网站数据分析等,其实获取IP地址很简单$_SERVER[\'REMOTE_ADDR\']就可以了。下面我们就来给大家汇总一下常用的几种获取IP地址的方法。

//方法1:

$ip = $_SERVER["REMOTE_ADDR"]; echo $ip;

//方法2:

复制代码 代码如下:


$user_IP = ($_SERVER["HTTP_VIA"]) ? $_SERVER["HTTP_X_FORWARDED_FOR"] : $_SERVER["REMOTE_ADDR"];
$user_IP = ($user_IP) ? $user_IP : $_SERVER["REMOTE_ADDR"];
echo $user_IP;


//方法3:

function getRealIp() { $ip=false; if(!empty($_SERVER["HTTP_CLIENT_IP"])){ $ip = $_SERVER["HTTP_CLIENT_IP"]; } if (!empty($_SERVER['HTTP_X_FORWARDED_FOR'])) { $ips = explode (", ", $_SERVER['HTTP_X_FORWARDED_FOR']); if ($ip) { array_unshift($ips, $ip); $ip = FALSE; } for ($i = 0; $i < count($ips); $i++) { if (!eregi ("^(10│172.16│192.168).", $ips[$i])) { $ip = $ips[$i]; break; } } } return ($ip ? $ip : $_SERVER['REMOTE_ADDR']); } echo getRealIp();

//方法4:

if ($HTTP_SERVER_VARS["HTTP_X_FORWARDED_FOR"]) { $ip = $HTTP_SERVER_VARS["HTTP_X_FORWARDED_FOR"]; } elseif ($HTTP_SERVER_VARS["HTTP_CLIENT_IP"]) { $ip = $HTTP_SERVER_VARS["HTTP_CLIENT_IP"]; } elseif ($HTTP_SERVER_VARS["REMOTE_ADDR"]) { $ip = $HTTP_SERVER_VARS["REMOTE_ADDR"]; } elseif (getenv("HTTP_X_FORWARDED_FOR")) { $ip = getenv("HTTP_X_FORWARDED_FOR"); } elseif (getenv("HTTP_CLIENT_IP")) { $ip = getenv("HTTP_CLIENT_IP"); } elseif (getenv("REMOTE_ADDR")) { $ip = getenv("REMOTE_ADDR"); } else { $ip = "Unknown"; } echo $ip ;

//方法5:

if(getenv('HTTP_CLIENT_IP')) { $onlineip = getenv('HTTP_CLIENT_IP'); } elseif(getenv('HTTP_X_FORWARDED_FOR')) { $onlineip = getenv('HTTP_X_FORWARDED_FOR'); } elseif(getenv('REMOTE_ADDR')) { $onlineip = getenv('REMOTE_ADDR'); } else { $onlineip = $HTTP_SERVER_VARS['REMOTE_ADDR']; } echo $onlineip;

//方法6:

print "您的IP地址是:"; if(!empty($_SERVER["HTTP_CLIENT_IP"])){ $cip = $_SERVER["HTTP_CLIENT_IP"]; } elseif(!empty($_SERVER["HTTP_X_FORWARDED_FOR"])){ $cip = $_SERVER["HTTP_X_FORWARDED_FOR"]; } elseif(!empty($_SERVER["REMOTE_ADDR"])){ $cip = $_SERVER["REMOTE_ADDR"]; } else{ $cip = "无法获取!"; } print $cip;

以上所述就是本文的全部内容了,希望对大家学习php能够有所帮助。
