Question

是否可以以简化的方式多次实例化同一个类，而不是我拥有的？

include ("php/functions.php");

date_default_timezone_set('Europe/Lisbon');

require 'php/gapi.class.php';
$ga1 = new gapi('XXXX@gmail.com','XXXX');
$ga2 = new gapi('XXXX@gmail.com','XXXX');
$ga3 = new gapi('XXXX@gmail.com','XXXX');

$ga1->requestReportData( $report_id = XXXX, $dimension = array('browser'), $metrics = array('visitors','pageviews','visits'), $sort_metric = '-visitors', $filter = 'browser == Firefox || browser == Chrome || browser == Internet Explorer || browser == Safari || browser == Opera && visits > 10', $start_date = '2012-10-17' );

$ga2->requestReportData( $report_id = XXXX, $dimension = array('country'), $metrics = array('visitors','pageviews','visits'), $sort_metric = '-visits', $filter = 'country != (not set) && visits > 3', $start_date = '2012-10-17', null, null, 10 );

$date2 = date('Y-m-d', mktime(0, 0, 0, date("m"), date("d")-15, date("Y")));
$today = date('Y-m-d');
$ga3->requestReportData($report_id = XXXX, $dimension = array('date'), $metrics = array('pageviews','visits'), $sort_metric = array('date')  , $filter = '',$date2,$today, null,15);

PS：此代码按预期工作......我只是想知道是否有更有效的方法来实现这一目标......

编辑：要回答一些关于所提供的解决方案的问题，这里是一个应用程序的例子，几百行后来在同一个文件中：

      <h2 class="verde">By country (10 relvant results)</h2>
      [useless code ommited...]
      <tbody>
        <?php
        $tp = 0;
        foreach($ga2->getResults() as $r2){
          if($tp==10) break;
        ?>
        <tr>
          <td><?php echo $r2 ?></td>
          <td><?php echo $r2->getVisitors() ?></td>
          <td><?php echo $r2->getVisits() ?></td>
          <td><?php echo $r2->getPageviews() ?></td>
        </tr>
        <?php
        $tp++;
        }
        ?>
        <tr style="font-weight:700">
          <td><strong>TOTAIS</strong></td>
          <td><strong><?php echo $ga2->getVisitors() ?></strong></td>
          <td><strong><?php echo $ga2->getVisits() ?></strong></td>
          <td><strong><?php echo $ga2->getPageviews() ?></strong></td>
        </tr>
      </tbody>

Answer 1

您只需要one object即可访问某个功能。您可以根据需要更改传递给函数的参数。

拥有相同类的multiple objects并不是有效的代码，因为每个对象占用了更多的额外内存。

因此，你只需要，

 $ga = new gapi('XXXX@gmail.com','XXXX');
 $ga->requestReportData( $report_id = XXXX, $dimension = array('browser'), $metrics =   array('visitors','pageviews','visits'), $sort_metric = '-visitors', $filter = 'browser == Firefox || browser == Chrome || browser == Internet Explorer || browser == Safari || browser == Opera && visits > 10', $start_date = '2012-10-17' );
 $ga->requestReportData( $report_id = XXXX, $dimension = array('country'), $metrics = array('visitors','pageviews','visits'), $sort_metric = '-visits', $filter = 'country != (not set) && visits > 3', $start_date = '2012-10-17', null, null, 10 );
 $date2 = date('Y-m-d', mktime(0, 0, 0, date("m"), date("d")-15, date("Y")));
 $today = date('Y-m-d');
 $ga->requestReportData($report_id = XXXX, $dimension = array('date'), $metrics = array('pageviews','visits'), $sort_metric = array('date')  , $filter = '',$date2,$today, null,15);

Answer 2

我假设您的电子邮件地址相同，因此您只需要一个对象。

include ("php/functions.php");

date_default_timezone_set('Europe/Lisbon');

require 'php/gapi.class.php';
$ga1 = new gapi('XXXX@gmail.com','XXXX');

$ga1->requestReportData( $report_id = XXXX, $dimension = array('browser'), $metrics = array('visitors','pageviews','visits'), $sort_metric = '-visitors', $filter = 'browser == Firefox || browser == Chrome || browser == Internet Explorer || browser == Safari || browser == Opera && visits > 10', $start_date = '2012-10-17' );

$ga1->requestReportData( $report_id = XXXX, $dimension = array('country'), $metrics = array('visitors','pageviews','visits'), $sort_metric = '-visits', $filter = 'country != (not set) && visits > 3', $start_date = '2012-10-17', null, null, 10 );

$date2 = date('Y-m-d', mktime(0, 0, 0, date("m"), date("d")-15, date("Y")));
$today = date('Y-m-d');
$ga1->requestReportData($report_id = XXXX, $dimension = array('date'), $metrics = array('pageviews','visits'), $sort_metric = array('date')  , $filter = '',$date2,$today, null,15);

不需要多次实例化同一个对象。

Answer 3

好吧，可能会有所帮助：

$ga1 = new gapi('XXXX@gmail.com','XXXX');
$ga2 = clone $ga1;

Answer 4

最大的问题是：多次实例化gapi类是否有意义？它是否是您尝试解决的“问题”的有效解决方案？在大多数情况下，您可以将相同的对象实例化数千次，并且不会产生太大的差异（内存方面）。告诉您将所有对象合并到一个实例中的人完全忽略了OOP的观点。如果有同一个类的多个实例是有意义的，请不要为了微优化而更改该类。

Answer 5

在您的代码示例中，实际上这些调用是多余的：

$ga1->requestReportData( $report_id = XXXX, $dimension = array('browser'), $metrics = array('visitors','pageviews','visits'), $sort_metric = '-visitors', $filter = 'browser == Firefox || browser == Chrome || browser == Internet Explorer || browser == Safari || browser == Opera && visits > 10', $start_date = '2012-10-17' );
$ga2->requestReportData( $report_id = XXXX, $dimension = array('country'), $metrics = array('visitors','pageviews','visits'), $sort_metric = '-visits', $filter = 'country != (not set) && visits > 3', $start_date = '2012-10-17', null, null, 10 );
$ga3->requestReportData($report_id = XXXX, $dimension = array('date'), $metrics = array('pageviews','visits'), $sort_metric = array('date')  , $filter = '',$date2,$today, null,15);

因为没有存储返回值。所以你可以把它们留下来。然后结果是，不需要三个对象$ga1到$ga3。所以，是的，你可以真正压缩它并保留任何这些对象。此外，不需要计算日期时间。

您的新文件：

<?php
/* space intentionally left blank */
?>

故事的道德：只要您不显示为什么您调用这些函数，就不能说如何改进代码。

返回的数据会怎样？
您是否在查询不同的API帐户？

实例化多次相同的PHP对象
