Question

我的功能基本上返回访问者的国家代码和另一个获取货币的功能。在Windows上运行XAMPP时，函数的返回值会像预期的那样回显。在Linux（eOS Loki）上，我手动安装了LAMPP堆栈（没有运行XAMPP），这次PHP不会回显函数的返回值。该页面将停止加载，没有错误。

注意：nhazi.dev是localhost

国家/地区代码功能

function get_ipinfo( $option )
{
  $url = "http://ipinfo.io/" . $_SERVER['REMOTE_ADDR'] . "/json";


  if($_SERVER['REMOTE_ADDR'] == '127.0.0.1') // I develop offline most times.
  {
    $url = "http://nhazi.dev/php_curl/json"; //Offline Debugging
  }

  $ch = curl_init($url);
  curl_setopt_array($ch, array(
    CURLOPT_RETURNTRANSFER => true
    )
  );

  $data = json_decode( curl_exec($ch) ); // decodes json response
  curl_close($ch);

  // Return value based on option
  if(! $option)
    return $data;
  if($option == 'ip')
    return $data->ip;
  if($option == 'city')
    return $data->city;
  if($option == 'region')
    return $data->region;
  if($option == 'country')
    return $data->country;
  if($option == 'location')
    return $data->loc;
  if($option == 'org')
    return $data->org;
}

货币代码功能

function get_currency( $countrycode )
{
    $url = "http://country.io/currency.json";

    if($_SERVER['REMOTE_ADDR'] == '127.0.0.1')
    {
        $url = "http://nhazi.dev/php_curl/currency"; //Offline Debugging
    }

    $ch = curl_init($url);
    curl_setopt_array($ch, array(
        CURLOPT_RETURNTRANSFER => true,
        )
    );
    $currency = json_decode(curl_exec($ch));
    // print_r($currency); // Debugging
    curl_close($ch);
    return $currency->$countrycode;
}

功能实施

<p>
    <?php echo get_currency( get_ipinfo('country') ); ?>
</p>
