thinkphp如何获取客户端IP,thinkphp获取ip
thinkphp框架中系统内置了get_client_ip方法用于获取客户端的IP地址,使用示例:
$ip = get_client_ip();
除了thinkphp内置get_client_ip函数外,也可使用下面函数获取客户端IP地址。
$type表示返回类型 0 返回IP地址, 1 返回IPV4地址数字
分享代码如下
function get_client_ip($type = 0) { $type = $type ? 1 : 0; static $ip = NULL; if ($ip !== NULL) return $ip[$type]; if (isset($_SERVER['HTTP_X_FORWARDED_FOR'])) { $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['HTTP_CLIENT_IP'])) { $ip = $_SERVER['HTTP_CLIENT_IP']; }elseif (isset($_SERVER['REMOTE_ADDR'])) { $ip = $_SERVER['REMOTE_ADDR']; } // IP地址合法验证 $long = ip2long($ip); $ip = $long ? array($ip, $long) : array('0.0.0.0', 0); return $ip[$type];
希望本文对大家深入学习php程序设计有所帮助。
