1个项目的php循环需要3个项目

Question

我有一个插件，可以让我一个接一个地显示问题， 但我需要它显示3的问题3。

$questions = $this->test->buildQuestions();
$answered  = $this->answeredQuestions->count();
foreach ($questions as $q => $question) {
  $records = fRecordSet::buildFromArray('WpTesting_Model_Question', array($q => $question));
  $isCurrent = ($answered == $q);
  $this->addStep(new WpTesting_Model_Step('', $records), $isCurrent);
}
return $this->enableStepsCounter();

如何使此代码打印3个问题而不是1个问题？

谢谢
