Ruby:关联数组 [英] Ruby : Associative Arrays

问题描述

Ruby on Rails是否具有关联数组?

Does Ruby on rails have associative arrays?

例如:

   a = Array.new
   a["Peter"] = 32
   a["Quagmire"] = 'asdas'

在Ruby中创建这种数组结构的最简单方法是什么?

What is the easiest method to create such an array structure in Ruby?

推荐答案

与PHP中的将数组和哈希值变混的PHP不同，在Ruby(以及几乎所有其他语言)中，它们是独立的.

Unlike PHP which conflates arrays and hashes, in Ruby (and practically every other language) they're a separate thing.

以您的情况为例:

a = {'Peter' => 32, 'Quagmire' => 'asdas'}
