Processing Multidimensional JSON Array with PHP
提问by 0xDECAFBAD
This is the json that deepbit.net returns for my Bitcoin Miner worker. I'm trying to access the workers array and loop through to print the stats for my [email protected] worker. I can access the confirmed_reward, hashrate, ipa, and payout_history, but i'm having trouble formatting and outputting the workers array.
这是 deepbit.net 为我的 Bitcoin Miner 工人返回的 json。我正在尝试访问工作人员数组并循环打印 [email protected] 工作人员的统计信息。我可以访问confirmed_reward、hashrate、ipa 和payout_history，但是我在格式化和输出workers 数组时遇到问题。
{
"confirmed_reward":0.11895358,
"hashrate":236.66666667,
"ipa":true,
"payout_history":0.6,
"workers":
{
"[email protected]":
{
"alive":false,
"shares":20044,
"stales":51
}
}
}
Thank you for your help :)
感谢您的帮助 ：）

I assume you've decoded the string you gave with json_decodemethod, like...
我假设你已经解码了你用json_decode方法给出的字符串，比如......
$data = json_decode($json_string, TRUE);
To access the stats for the particular worker, just use...
要访问特定工作人员的统计信息，只需使用...
$worker_stats = $data['workers']['[email protected]'];
To check whether it's alive, for example, you go with...
例如，要检查它是否还活着，您可以使用...
$is_alive = $worker_stats['alive'];
It's really that simple. )
真的就是这么简单。)

Why don't you use json_decode.
你为什么不使用json_decode。
You pass the string and it returns an object/array that you will use easily than the string directly.
您传递字符串并返回一个对象/数组，您将比直接使用字符串更容易使用。
To be more precise :
更准确地说：
<?php
$aJson = json_decode('{"confirmed_reward":0.11895358,"hashrate":236.66666667,"ipa":true,"payout_history":0.6,"workers":{"[email protected]":{"alive":false,"shares":20044,"stales":51}}}');
$aJson['workers']['[email protected]']; // here's what you want!
?>

You can use json_decodeto get an associative array from the JSON string.
您可以使用json_decode从 JSON 字符串中获取关联数组。
In your example it would look something like:
在您的示例中，它看起来像：
$json = 'get yo JSON';
$array = json_decode($json, true); // The `true` says to parse the JSON into an array,
// instead of an object.
foreach($array['workers']['[email protected]'] as $stat => $value) {
// Do what you want with the stats
echo "$stat: $value<br>";
}
回答by AndreKR
$result = json_decode($json, true); // true to return associative arrays
// instead of objects
var_dump($result['workers']['[email protected]']);
