php - 循环遍历复杂的json对象php

问题描述

好的，我必须遍历 nanopool 中的 json 对象。

我的 php 代码来获取 json 并对其进行解码：

$json = file_get_contents("https://api.nanopool.org/v1/eth/payments/0x218494b2284a5f165ff30d097d3d7a542ff0023B");

$decode =  json_decode($json);

json var_dump 如下：

    object(stdClass)#1 (2){
  [
    "status"
  ]  => bool(true)  [
    "data"
  ]  => array(9)  {
    [
      0
    ]    => object(stdClass)#2 (4)    {
      [
        "date"
      ]      => int(1526913390)      [
        "txHash"
      ]      => string(66) "0xd55f83fd04fba6bf47f77494c2348417ae892199ec5a3037d5731acdf4b51c53"      [
        "amount"
      ]      => float(1.00284502876)      [
        "confirmed"
      ]      => bool(true)
    }    [
      1
    ]    => object(stdClass)#3 (4)    {
      [
        "date"
      ]      => int(1526625835)      [
        "txHash"

        "amount"
      ]      => float(1.00043622303)      [

    }
  }
}

现在我想遍历所有的 json 并提取每个“记录”的日期和数量，代码如下：

foreach($decode as $item) { 
    $date = $item['date'];
    $amount = $item['amount'];
}

但它不起作用。非常欢迎在此问题上提供任何帮助以正确提取所需数据

有什么帮助吗？

解决方案

用作true第二个参数json_decode()将json数据转换为普通PHP数组

$decode =  json_decode($json,true);

现在迭代它并获取数据

foreach($decode['data'] as $val){
   echo date('Y-m-d',$val['date']).'--'.$val['amount'];
   echo "<br/>";
}

输出：- https://prnt.sc/jlkak3
