目前有两种方法 1、使用THINKPHP自带的 get_client_ip() 方法 2、使用PHP自带的 $_SERVER['REMOTE_ADDR'] 也可以获取
function get_client_ip(){ if (getenv("HTTP_CLIENT_IP") && strcasecmp(getenv("HTTP_CLIENT_IP"), "unknown")){ $ip = getenv("HTTP_CLIENT_IP"); }else if (getenv("HTTP_X_FORWARDED_FOR") && strcasecmp(getenv("HTTP_X_FORWARDED_FOR"), "unknown")){ $ip = getenv("HTTP_X_FORWARDED_FOR"); }else if (getenv("REMOTE_ADDR") && strcasecmp(getenv("REMOTE_ADDR"), "unknown")){ $ip = getenv("REMOTE_ADDR"); }else
if (isset($_SERVER['REMOTE_ADDR']) && $_SERVER['REMOTE_ADDR']
&& strcasecmp($_SERVER['REMOTE_ADDR'], "unknown")){ $ip = $_SERVER['REMOTE_ADDR']; }else{ $ip = "unknown";
} return($ip); }
