PHP动态变量名称

Question

I want a dynamic property name like this: 我想要这样的动态属性名称：

$_taxVocabName = 'name';
$node->field_ . $_taxVocabName;

This should call: 这应该调用：

$node->field_name

How can I do this? 我怎样才能做到这一点？

I could not find anything on php.net or elsewhere. 我在php.net或其他地方找不到任何内容。

Answer 1

Two ways: 两种方式：

First, use a variable: 首先，使用一个变量：

$property = 'field_' . $_taxVocabName;

$node->$property;

Second, use curly brackets: 其次，使用大括号：

$node->{'field_' . $_taxVocabName};

Answer 2

I'd think a much better way to do this would be 我认为一种更好的方法是

$taxVocabName = "name";
$property = "field_" . $taxVocabName;

Then you would have to set the variable to a value of course... 然后，您必须将变量设置为一个当然的值...

like so: 像这样：

$$property = "My variable variable";

or: 要么：

$field_name = "My variable variable";

I know it's a bit later, but maybe this will help someone else down the road. 我知道会晚一点，但是也许这会帮助其他人。
