Symfony2:配置 yaml 中的引用字符串或数组 [英] Symfony2: Reference string or an array in config yaml

问题描述

在 symfony2 中我使用了下面的配置 yaml:

In symfony2 I used config yaml below:

// config.yml
parameters:
  something: 
    content: 
      price:  2.30
      mainText: 'Some text here.'
      redText:  'This is a text here plus price: ' %price%

%price% 错误并给我一个错误，但系统告诉它一个数组，那么如何指向某物['content'][price]?

The %price% is wrong and gives me an error but system tells its an array, so how to point to something['content'][price]?

推荐答案

您可以这样做

parameters:
    something.content.price: 2.30
    something:
        content:
            mainText: 'Some text here.'
            redText:  'This is a text here plus price: %something.content.price%'

这里我们只有 2 个参数，something.content.price 包含一个浮点数，something 包含一个数组.

Here we only have 2 parameters, something.content.price that contains a float, and something that contains an array.

这意味着您只能直接访问 DI 配置中的这两个.

This means you will only be able to access directly those 2, inside the DI configuration.
