Question

我有像这样的json格式

{"January":1,"February":2,"March":3,"April":0,"May":0,"June":0,"July":0,"August":0,"September":0,"October":0,"November":0,"December":0}

我希望有两个阵列可以像这样输出

arry1 = [January,February,March ...]
arry2 = [1,2,3...]

如何在不通过子字符串函数的情况下执行此操作，因为这将是一个更长的方法，php具有此内置功能

Answer 1

您不需要循环来将键与值分开。 php具有隔离键和值的功能......

代码：（Demo）

$json = '{"January":1,"February":2,"March":3,"April":0,"May":0,"June":0,"July":0,"August":0,"September":0,"October":0,"November":0,"December":0}';

$decoded = json_decode($json, true);  // decode as an array
$arry1 = array_keys($decoded);        // isolate the keys
$arry2 = array_values($decoded);      // isolate (and re-index) the values

echo "\$arry1: ";
var_export($arry1);
echo "\n---\n\$arry2: ";
var_export($arry2);

输出：

$arry1: array (
  0 => 'January',
  1 => 'February',
  2 => 'March',
  3 => 'April',
  4 => 'May',
  5 => 'June',
  6 => 'July',
  7 => 'August',
  8 => 'September',
  9 => 'October',
  10 => 'November',
  11 => 'December',
)

$arry2: array (
  0 => 1,
  1 => 2,
  2 => 3,
  3 => 0,
  4 => 0,
  5 => 0,
  6 => 0,
  7 => 0,
  8 => 0,
  9 => 0,
  10 => 0,
  11 => 0,
)

这样的事情会对你有用：

<?php

// Put the json object into a variable
$jsonObject = '{"January":1,"February":2,"March":3,"April":0,"May":0,"June":0,"July":0,"August":0,"September":0,"October":0,"November":0,"December":0}';

// Decode the json object
$jsonDecodeValues= json_decode($jsonObject);

// Create an array for months and day numbers
$monthNameArray = array();
$monthNumberArray = array();

// Loop through the decoded values and add them to the month/number variables
foreach ($jsonDecodeValues as $jsonDecodeKey => $jsonDecodeValue) {
    $monthNameArray[] = $jsonDecodeKey;
    $monthNumberArray[] = $jsonDecodeValue ;
}

仅在php中设置对象名称，并用逗号分隔值
