在GeoIP2中找不到读卡器类

Question

我正在尝试安装Maxmind的GeoIP2。我按照他们的指示做了所有的事情，但我仍然得到这个恼人的错误：

Fatal error: Class 'GeoIp2\Database\reader' not found in C:\Program Files\*\*\localweb\GeoIp2\index.php on line 19

下面是脚本在index.php中的外观：

<?php
require_once 'vendor/autoload.php';
use GeoIp2\Database\reader;
// This creates the Reader object, which should be reused across
// lookups.
$reader = new Reader('C:/Program Files/*/*/localweb/GeoIp2/Database/GeoLite2-Country.mmdb');
$record = $reader->country('128.101.101.101');
?>

有人能帮上忙吗？

Answer 1

这对我很有效，谢谢@Greg Oschwald！因为我没有使用composer，所以我现在的代码是：

<?php
require 'geoip2.phar';
try {
    $reader = new GeoIp2\Database\Reader('GeoLite2-City.mmdb');
    $record = $reader->city('128.101.101.101');
    print($record->country->isoCode . "\n"); // 'US'
    print($record->country->name . "\n"); // 'United States'
    print($record->country->names['zh-CN'] . "\n"); // '??'
    print($record->mostSpecificSubdivision->name . "\n"); // 'Minnesota'
    print($record->mostSpecificSubdivision->isoCode . "\n"); // 'MN'
    print($record->city->name . "\n"); // 'Minneapolis'
    print($record->postal->code . "\n"); // '55455'
    print($record->location->latitude . "\n"); // 44.9733
    print($record->location->longitude . "\n"); // -93.2323
} catch (Exception $e) {
    echo 'Could not open Phar: ', $e;
}

从https://github.com/maxmind/GeoIP2-php/releases获取了phar文件
