php中函数返回的访问数组 [英] Access array returned by a function in php

问题描述

我正在使用一个模板引擎，它可以在我的网站中插入我想要的代码.

I'm using a template engine that inserts code in my site where I want it.

我写了一个函数来测试一些很简单的东西:

I wrote a function to test for something which is quite easy:

myfunction() { return '($this->data["a"]["b"] ? true : false)'; }

问题是，$this->data是私有的，到处都无法访问，所以不得不使用getData();这导致了我的问题.

The problem is, $this->data is private, and I can't access it everywhere, so I have to use getData(); which causes my problem.

$this->getData()['a']['b']

不起作用，首先赋值也不起作用，因为它将直接在 if() 块中使用.

does not work, and assigning the value first doesn't either because it will be used directly in an if() block.

有什么想法吗?

推荐答案

自 PHP 5.4 起，完全可以做到这一点:

Since PHP 5.4 it's possible to do exactly that:

getSomeArray()[2]

参考:https://secure.php.net/manual/en/language.types.array.php#example-62

在 PHP 5.3 或更早版本中，您需要使用临时变量.

On PHP 5.3 or earlier, you'll need to use a temporary variable.
