Answer 1

你有一个多维数组。你想试试这个：

echo $arr[0]['current_location']['city'];
echo $arr[0]['current_location']['country'];

Answer 2

像这样：

echo $somearray[0]['current_location']['city'];
echo $somearray[0]['current_location']['country'];

Answer 3

正如已经指出的那样，你有一个多维数组 - 换句话说就是一个数组中的数组。

这种数据通常是这样访问的：

foreach ($yourArray as $data) {
    $locationData = $data['current_location'];

    echo "user id " . $data['uid'] . "\n";
    echo " - city " . $locationData['city'] . "\n";
    echo " - country " . $locationData['country'] . "\n";
}

因此，如果数据中出现多个用户，则可以处理每个用户。
