PHP多维数组JSON [英] PHP multidimensional array to JSON

问题描述

所以我尝试找出最佳的方式来获得MySQL表的数据变成一个多维PHP数组或多维数组转换成JSON字符串。

So im trying to figure out the best way to get MySql table data into either a multidimensional PHP array or convert that multidimensional array into a json string.

基本上什么即时试图做的是有一个PHP包括返回JSON字符串，所以我可以通过它进行迭代。我需要有多个值的单个密钥，所以我不会100％地肯定，即时通讯在正确的方向前进。

Essentially what im trying to do is have a php include that returns the JSON string so i can iterate through it. I am needing a single key with multiple values, so im not 100% sure that im headed in the right direction.

我要多个值分配给同一键，例如：

I want to assign multiple values to the same key, for example:

[{"key1": "package1", "package2", "package3"}, {"key2": "package1", "package2", "package3", "package4"}]

我认为是不会工作的权利？因为我没有任何类型指数的呢？

I think that is not going to work right? Because i dont have any type of index's?

推荐答案

这是无效的JSON。你正在寻找的结构是这样的：

That is not valid JSON. The structure you are looking for would be something like:

[
 {"key1": ["package1", "package2", "package3"]},
 {"key2": ["package1", "package2", "package3", "package4"}]
          ^ An array as the value to the key "key1", "key2", etc..
]

在PHP的一面，你需要这样的：

At the PHP side, you would need something like:

1. 对于每一行从MySQL中取出
   
   
   
   • $改编[$关键] =＆LT;新数组>
   
   
   • 每个包：
     
     
     
     • 追加包 $改编[$关键]
     
     

1. For every row fetched from MySQL
   • $arr[$key] = <new array>
   • for each package:
     • append package to $arr[$key]
