下面我有一个在CMSMS中的事件期间传递的对象参数的print_r输出。我是php和CMSMS的新手。我特别需要id为11（persontasked）的对象的值，但我不知道从哪里开始。看起来它是一个带有一些参数的对象，其中一个是一个对象（fielddefs），它包含数组，我需要的值也在一个对象中。有没有一种简单的方法来浏览这个结构？它总是位于同一个地方。
这是包含我需要的值的块（Jon Smith）：
[storage:ArrayObject:private] => Array
(
[0] => Jon Smith
)
位于此对象的深处：

答案 0 :(得分：1)
您遇到的问题是storage属性私有，因此无法从ListIt2FielddefArray对象的实例外部访问。
您需要一个getter方法来访问该值。
它应该类似于：
<?php
$myobject->get('myval');
//or
$myobject->getStorage();
?>
基本上，必须有可公开访问的内容，以便您访问这些值。
如果你发布这些课程的实际代码，它会让我们更好地了解你的选择。

我认为print_r让它看起来比它实际上要复杂得多。我能够得到这个价值：
$itemobject = $params['item_object'];
$itemobjectArray = (array)$itemobject;
$fielddefsArray=$itemobjectArray['fielddefs'];
$output = $fielddefsArray[11];`enter code here`
答案 2 :(得分：0)
即使打印为完整对象。
它已实现，因此您可以使用别名直接访问字段：
echo $item->persontasked; //this should print "Jon Smith"
public function __get($key)
{
if(isset($this->fielddefs[$key]))
return $this->fielddefs[$key]->GetValue();
}
