我正在使用这个脚本来找出当天的每日访问者和总浏览量。

 <?xml version="1.0" ?> 
- <aws:UrlInfoResponse xmlns:aws="http://alexa.amazonaws.com/doc/2005-10-05/">
- <aws:Response xmlns:aws="http://awis.amazonaws.com/doc/2005-07-11">

- <aws:UrlInfoResult>
- <aws:Alexa>
- <aws:TrafficData>

- <aws:UsageStatistic>
- <aws:TimeRange>
  <aws:Months>1</aws:Months> 
  </aws:TimeRange>
- <aws:Rank>
  <aws:Value>2426210</aws:Value> 
  <aws:Delta>-12536204</aws:Delta> 
  </aws:Rank>
- <aws:Reach>
- <aws:Rank>
  <aws:Value>2757065</aws:Value> 
  <aws:Delta>-12015838</aws:Delta> 
  </aws:Rank>
- <aws:PerMillion>
  <aws:Value>0.4</aws:Value> 
  <aws:Delta>+1200%</aws:Delta> 
  </aws:PerMillion>
  </aws:Reach>
- <aws:PageViews>

  <aws:Value>0.21</aws:Value> 
  <aws:Delta>+4000%</aws:Delta> 
  </aws:PerMillion>
- <aws:Rank>
  <aws:Value>2206561</aws:Value> 
  <aws:Delta>-12826154</aws:Delta> 
  </aws:Rank>
- <aws:PerUser>
  <aws:Value>3</aws:Value> 
  <aws:Delta>+200%</aws:Delta> 
  </aws:PerUser>
  </aws:PageViews>
  </aws:UsageStatistic>
  </aws:UsageStatistics>
  <aws:ContributingSubdomains /> 
  </aws:TrafficData>
  </aws:Alexa>
  </aws:UrlInfoResult>
- <aws:ResponseStatus xmlns:aws="http://alexa.amazonaws.com/doc/2005-10-05/">
  <aws:StatusCode>Success</aws:StatusCode> 
  </aws:ResponseStatus>
  </aws:Response>
  </aws:UrlInfoResponse>

该文件保存在服务器的某个位置。

使用此代码获取

$xml = simplexml_load_file("PATH To FILE", null, null, 'aws', true);
$pageview=$income_data->Response->UrlInfoResult->Alexa->TrafficData->UsageStatistics->UsageStatistic->PageViews->PerMillion->Value;

$daily_pageview=$pageview*10;

一切都很好，直到我发现结果对于少数域值都不正确。然后我尝试回显每个值，我发现它忽略了点之后的值（。）

[Like for example]
.02=>0
.100=>0
1.02=>1

在上述情况下，值$pageview=0.21和输出是0但它应该来2.1。

对此的任何帮助将不胜感激..

我猜这是从 SimpleXMLElement 中转换值的方式，至少这是下面所指的。

<?php
$xml = '
<testdata>
    <foo>1.2</foo>
</testdata>
';

$xml = new SimpleXMLElement($xml);

echo get_class($xml->foo);  //SimpleXMLElement

echo 1.2 * 2;               // 2.4
echo $xml->foo * 2;         // 2
echo (float)$xml->foo * 2;  // 2.4
