方法一：
publicfunctionindex($type=0,$adv=false)
{
$type=$type?1:0;
static$ip=NULL;
if($ip!==NULL)return$ip[$type];
if($adv){
if(isset($_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'];
}
}elseif(isset($_SERVER['REMOTE_ADDR'])){
$ip=$_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];
$a=$ip[$type]
dump($a);
exit;
}
方法二：
引入
use \think\Request;
echo '访问ip地址：' . $request->ip() .
上面扯大了，哈哈;
