访问对象的属性，就像对象是数组一样 [英] Accessing object's properties like if the objects were arrays

问题描述

当您不知道对象的名称将如何书写时，是否可以访问对象的属性?

Is it possible to access object's properties, when you don't know just how their names will be written?

我的问题是，当查询返回 Zend_Db_Table_Rowset_Abstract 对象时，有一些字段的名称类似于name_fr"、name_en"、name_au".我想根据应用程序中使用的当前语言访问它们中的任何一个.为了实现这一点，我这样编写代码:

My problem is that when a query returns Zend_Db_Table_Rowset_Abstract object, there are some fields with names like "name_fr", "name_en", "name_au". I want to access either of them according to the current language used in the application. To achieve this I write the code this way:

$result = $myModel->fetchAll($query)->current();
$row = $result->toArray();
echo 'Your name is '.$row['name_'.$language];

这很烦人.是否可以编写这样的代码，例如:

This is very annoying. Is it possible to write a code like this for example:

$result = $myModel->fetchAll($query)->current();
echo 'Your name is '.$result->name_{$language};

推荐答案

这应该有效:

$result = $myModel->fetchAll($query)->current();
echo 'Your name is '.$result->{'name_'.$language};
