动态创建对象实例名称

Seavers

我有一个在其他地方动态创建的星期数组（这是print_r转储）：

  array:28 [▼
  “week1” => “2018-03-01”
  “week2” => “2018-03-08”
  “week3” => “2018-03-15”
  “week4” => “2018-03-22”
  “week5” => “2018-03-29”
  “week6” => “2018-04-05”
  “week7” => “2018-04-12”
  “week8” => “2018-04-19”
  “week9” => “2018-04-26”
  “week10” => “2018-05-03”
  “week11” => “2018-05-10”
  “week12” => “2018-05-17”
  “week13” => “2018-05-24”
  “week14” => “2018-05-31”
  “week15” => “2018-06-07”
  “week16” => “2018-06-14”
  “week17” => “2018-06-21”
  “week18” => “2018-06-28”
  “week19” => “2018-07-05”
  “week20” => “2018-07-12”
  “week21” => “2018-07-19”
  “week22” => “2018-07-26”
  “week23” => “2018-08-02”
  “week24” => “2018-08-09”
  “week25” => “2018-08-16”
  “week26” => “2018-08-23”
  “week27” => “2018-08-30”
  “week28” => “2018-09-06”
]

对于这两个星期中的每个星期，我都希望创建一个Google_Service_AnalyticsReporting_DateRange对象的实例，以便可以在同一批调用中查询多个日期范围。

但是，根据Google Analytics Reporting API V4，我必须创建具有不同名称的实例：

样品 Analytics Reporting API v4 | Google开发人员

特别：

$march = new Google_Service_AnalyticsReporting_DateRange();
$march->setStartDate(“2015-03-01”);
$march->setEndDate(“2015-03-31”);

$January = new Google_Service_AnalyticsReporting_DateRange();
$January->setStartDate(“2015-01-01”);
$January->setEndDate(“2015-01-31”);

我的问题是我无法弄清楚是否有可能循环遍历几周数组以动态创建多个实例（名称不同）。这是我的方法：

private function get_timeline_report($analytics, $campaign_start_date, $dates, $expression=null, $alias=null, $filter=null, User $user)
{
    $dates = (array_values($dates));

    foreach ($dates as $key => $value)
    {
        // todo - need to get date and give it a name (week1 etc - see http://www.php.net/manual/en/language.oop5.basic.php#language.oop5.basic.newx)
        // Create the DateRange object.
        $date_ranges[$key] = new Google_Service_AnalyticsReporting_DateRange();
        $date_ranges[$key]->setStartDate($campaign_start_date);
        $date_ranges[$key]->setEndDate($value);
    }

    // Create the Metrics object.
    $sessions = new Google_Service_AnalyticsReporting_Metric();
    $sessions->setExpression($expression);
    $sessions->setAlias($alias);

    // Create the ReportRequest object.
    $request = new Google_Service_AnalyticsReporting_ReportRequest();
    $request->setViewId($user->ga_view_id);
    $request->setDateRanges($date_ranges);
    $request->setMetrics($sessions);
    $request->setFiltersExpression($filter);

    $body = new Google_Service_AnalyticsReporting_GetReportsRequest();
    $body->setReportRequests(array($request));

    return $analytics->reports->batchGet($body);
}

是否可以动态创建实例名称，如果可以，如何创建？当前代码返回此Google服务异常：

初级

您问了一个错误的问题，因为您的错误实际上并非来自对象实例的名称。在多个日期范围内的google示例中，我们可以注意到：

 $request->setDateRanges(array($march, $january));

如您所见，此数组根本没有关联。因此我们可以得出结论，Google Api不会使用所有实例名称，而只会使用dateRange实例本身。因此您的第一个代码可能会很好用，而不是：

foreach ($dates as $key => $value)
    {
        // Create the DateRange object.
        $date_ranges[$key] = new Google_Service_AnalyticsReporting_DateRange();
        $date_ranges[$key]->setStartDate($campaign_start_date);
        $date_ranges[$key]->setEndDate($value);
    }

您使用类似：

$i=0;
foreach ($dates as $key => $value)
{
    // Create the DateRange object.
    $date_ranges[$i] = new Google_Service_AnalyticsReporting_DateRange();
    $date_ranges[$i]->setStartDate($campaign_start_date);
    $date_ranges[$i]->setEndDate($value);
    $i++;
}
unset($i,$key,$value);
