处理对象属性名称中的特殊字符 [英] Dealing with special characters in object property names

问题描述

我正在使用由大学教授的实习生创建的数据库.许多字段的名称都类似于"Revenues_(budget)".

I am working with a database created by a university professor's intern. Many of the fields have names like 'Revenues_(budget)'.

当前，当使用具有字段作为属性的对象时，我会做类似的事情

Currently when working with objects that have the fields as properties I do something like

$f = 'Revenues_(budget)';
echo $obj->$f;

这很好，但是我想知道是否可能有一种更优雅或更简洁的方式来处理这些问题?

This works fine but I was wondering if there might be a more elegant or at least concise way to handle these?

推荐答案

您可以在一个表达式中做到这一点:

You can do that in one expression:

echo $obj->{'Revenues_(budget)'};
