JSON to PHP Associative array
提问by vimist
would any of you know a good way to put this into an associative array . I have tried json_decodebut found it to not be much help.
你们中有人知道将它放入关联数组的好方法吗？我试过了，json_decode但发现它没有多大帮助。
This is the data i need to put into an associative array:
这是我需要放入关联数组的数据：
{
"data": [
{
"name": "Joe Bloggs",
"id": "203403465"
},
{
"name": "Fred Bloggs",
"id": "254706567"
},
{
"name": "Barny Rubble",
"id": "453363843"
},
{
"name": "Homer Simpson",
"id": "263508546"
}
]
}
EDIT:
编辑：
After I accepted the answer, I remembered why I thought that the json_decode wasn't working.
接受答案后，我想起了为什么我认为 json_decode 不起作用。
Instead of having an associative array like this:
而不是拥有这样的关联数组：
[0] => Array
(
[name] => Joe Bloggs
[id] => 203403465
)
I wanted one like this:
我想要一个这样的：
Array
(
[Joe Bloggs] => 45203340465
[Fred Bloggs] => 65034033446
)
Unfortunately, I had forgotten this at the time.. but I have resolved my issue now anyway.
不幸的是，我当时忘记了这一点......但我现在已经解决了我的问题。
Thanks for all of your help!
感谢您所有的帮助！

i asume your json comes via ajax.... (otherwise the code works with json_decode) so be sure the js json stringifys your object and
我假设你的 json 来自 ajax ......（否则代码与 json_decode 一起工作）所以确保 js json 字符串化你的对象和
you'll need to stripslashes before json_decode ;-) in php
你需要在 json_decode 之前去掉斜杠；-) 在 php 中

json_decodeworks for me on your data:
json_decode对我的数据有用：
print_r(json_decode('{
"data": [
{
"name": "Joe Bloggs",
"id": "203403465"
},
{
"name": "Fred Bloggs",
"id": "254706567"
},
{
"name": "Barny Rubble",
"id": "453363843"
},
{
"name": "Homer Simpson",
"id": "263508546"
}
]
}
', true));
Output:
输出：
Array
(
[data] => Array
(
[0] => Array
(
[name] => Joe Bloggs
[id] => 203403465
)
[1] => Array
(
[name] => Fred Bloggs
[id] => 254706567
)
[2] => Array
(
[name] => Barny Rubble
[id] => 453363843
)
[3] => Array
(
[name] => Homer Simpson
[id] => 263508546
)
)
)
Setting the second argument to truereturns an associative array.
将第二个参数设置为true返回关联数组。

You have to make a new array
你必须创建一个新数组
$json_array = json_decode($_POST['json'], true);
$assoc_array = array();
for($i = 0; $i < sizeof($json_array); $i++)
{
$key = $json_array[$i]['name'];
$assoc_array[$key] = $json_array[$i]['value'];
}
you will get your associative array in $assoc_array and you can now directly access using indexes.
您将在 $assoc_array 中获得关联数组，现在可以使用索引直接访问。
