1、ThinkPHP5通过助手函数即可获取
request()->ip()
2、通过自己解析
function get_client_ip($type = 0) { $type = $type ? 1 : 0; static $ip = NULL; if ($ip !== NULL) { return $ip[$type]; } if (isset($_SERVER['HTTP_X_REAL_IP'])) { //nginx 代理模式下,获取客户端真实IP $ip = $_SERVER['HTTP_X_REAL_IP']; } elseif (isset($_SERVER['HTTP_CLIENT_IP'])) { //客户端的ip $ip = $_SERVER['HTTP_CLIENT_IP']; } elseif (isset($_SERVER['HTTP_X_FORWARDED_FOR'])) { //浏览当前页面的用户计算机的网关 $arr = explode(',', $_SERVER['HTTP_X_FORWARDED_FOR']); $pos = array_search('unknown', $arr); if (false !== $pos) unset($arr[$pos]); $ip = trim($arr[0]); } elseif (isset($_SERVER['REMOTE_ADDR'])) { //浏览当前页面的用户计算机的ip地址 $ip = $_SERVER['REMOTE_ADDR']; } else { $ip = $_SERVER['REMOTE_ADDR']; } // IP地址合法验证 $long = sprintf("%u", ip2long($ip)); $ip = $long ? array($ip, $long) : array('0.0.0.0', 0); return $ip[$type]; }
