方法一:
//获取ip地址函数 function GetIP(){ if(!empty($_SERVER["HTTP_CLIENT_IP"])) $ip = $_SERVER["HTTP_CLIENT_IP"]; else if(!empty($_SERVER["HTTP_X_FORWARDED_FOR"])) $ip = $_SERVER["HTTP_X_FORWARDED_FOR"]; else if(!empty($_SERVER["REMOTE_ADDR"])) $ip = $_SERVER["REMOTE_ADDR"]; else $ip = "Unknown"; return $ip; } echo GetIP(); //调用函数
方法二:
//获取ip地址函数 function GetIp(){ if($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"; } return $ip; } echo GetIp();//调用函数
方法三:
$ip = $_SERVER["REMOTE_ADDR"]; echo $ip;
方法四:
//获取ip地址函数 function GetIp(){ $ip = ($_SERVER["HTTP_VIA"]) ? $_SERVER["HTTP_X_FORWARDED_FOR"] : $_SERVER["REMOTE_ADDR"]; $ip = ($user_IP) ? $user_IP : $_SERVER["REMOTE_ADDR"]; return $ip; } echo GetIp();//调用函数
方法五:
//获取ip地址函数 function GetIp(){ $ip=false; if(!empty($_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 GetIp();//调用函数
方法六:
//获取ip地址函数 function GetIp(){ if(getenv('HTTP_CLIENT_IP')){ $ip = getenv('HTTP_CLIENT_IP'); }elseif(getenv('HTTP_X_FORWARDED_FOR')){ $ip = getenv('HTTP_X_FORWARDED_FOR'); }elseif(getenv('REMOTE_ADDR')){ $ip = getenv('REMOTE_ADDR'); }else{ $ip = $HTTP_SERVER_VARS['REMOTE_ADDR']; } return $ip; } echo GetIp();//调用函数
