使用php拦截国家/地区IP

Question

所以我有以下代码：

        $ip = getenv('HTTP_CLIENT_IP') ?: getenv('HTTP_X_FORWARDED_FOR') ?: getenv('HTTP_X_FORWARDED') ?: getenv('HTTP_FORWARDED_FOR') ?: getenv('HTTP_FORWARDED') ?: getenv('REMOTE_ADDR');
        $details = json_decode(file_get_contents("http://ipinfo.io/$ip/json"));

    if ($details->country == US):
    {
       echo "We are sorry, We cannot allow users from United States";
       die();
    }
    elseif ($details->country == GB):
    {
       echo "We are sorry, We cannot allow users from United Kingdom";
       die();
{
else:
show index script

问题是，一些美国和英国用户仍然可以看到索引

Answer 1

看起来您正在与名为US或GB的常量进行比较。您可能想要检查字符串。

$details->country === 'US'。

Answer 2

问题出在http://ipinfo.io/$ip/json I get Rate limit exceeded。
