Question

我从对象方法返回一个值并将其放入数组中。代码如下：

$additionalTestConfirmation = array();

$additionalTests = $this->getAdditionalTestsSelected();


foreach($additionalTests as $availableTest)
{
  $additionalTestConfirmation = $availableTest->getName();

}

$appointment = $this->getAppointment();

$tokens = array(
  '%DATE%' => $this->getAppointment()->getDate(),
  '%LOCATION%' => $this->getAppointment()->getLocation(),
  '%TIME%' => $this->getTime(),
  '%ROOM%' => $this->getRoom(),
  '%NAME%' => ($this->getUser() ? $this->getUser()->getFullName() : null),
  '%TZ%'   => $this->getAppointment()->getShowTimeZone() ? $this->getAppointment()->getTimeZone() : '',
  '%AdditionalTestsSelected%' => $additionalTestConfirmation,
);

对于上面的代码，我收到一条系统错误消息：注意：/ Users / alexhu / NetBeansProjects / menagerie / svn / trunk / apps / frontend / modules / legacy / legacy_lib / lib / classes / AppointmentTime中的数组到字符串转换第379行.php。如何避免这种情况并获得我想要的$ availableTest-＆gt; getName（）返回值。感谢

Answer 1

foreach($additionalTests as $availableTest)
{
  $additionalTestConfirmation[] = $availableTest->getName();

}

在您发表评论后，我建议您：

$appointment = $this->getAppointment();

$token = array(
  '%DATE%' => $appointment->getDate(),
  '%LOCATION%' => $appointment->getLocation(),
  '%TIME%' => $this->getTime(),
  '%ROOM%' => $this->getRoom(),
  '%NAME%' => ($this->getUser() ? $this->getUser()->getFullName() : null),
  '%TZ%'   => $appointment->getShowTimeZone() ? $appointment->getTimeZone() : ''
  );

$tokens = array();

$additionalTests = $this->getAdditionalTestsSelected();

foreach($additionalTests as $availableTest)
{
  $token['%AdditionalTestsSelected%'] = $availableTest->getName();
  $tokens[] = $token;
}

// here comes logic for all tokens

Answer 2

为了将每个$ availableTest-＆gt; getName（）添加到数组$ additionalTestConfirmation，您需要在数组和赋值运算符[]上使用=

foreach($additionalTests as $availableTest)
{
  $additionalTestConfirmation[] = $availableTest->getName();

}

您还可以使用array_push

功能

Answer 3

将元素分配给数组时，必须指定索引，或使用空方括号（[]）添加项目：

foreach($additionalTests as $availableTest) {
  $additionalTestConfirmation[] = $availableTest->getName();
  // or array_push($additionalTestConfirmation, $availableTest->getName()); 
  // see: http://us3.php.net/array_push
}

有关详情，请参阅文档：http://php.net/manual/en/language.types.array.php

修改

另外，在这一行：

'%AdditionalTestsSelected%' => $additionalTestConfirmation,

...您正在将数组传递给此索引。如果代码后缀预期这是一个字符串，则可能导致错误。 * 这不会导致错误 - 将数组放入另一个数组是完全可以接受的。正如我所提到的，它实际上取决于使用$tokens数组的代码将执行和期望的内容。如果它需要AdditionalTestsSelected索引的纯字符串，则可能需要执行以下操作：

'%AdditionalTestsSelected%' => implode(',', $additionalTestConfirmation)

...使值成为逗号分隔列表。

另请注意，在该行的末尾您还有一个额外的逗号。
