如何在 PHP 中转换嵌套的 JSON 数组 [重复]

Question

我需要转换

h 这个 JSON：

["theory",["theory","theory of relativity","theory test","theory of everything","theory definition","theory of evolution","theory of mind","theory of a deadman","theory of love","theory meaning"]]

到一个数组，包括嵌套，在 PHP 中：

array (
  0 => 'theory',
  1 => 
  array (
    0 => 'theory',
    1 => 'theory of relativity',
    2 => 'theory test',
    3 => 'theory of everything',
    4 => 'theory definition',
    5 => 'theory of evolution',
    6 => 'theory of mind',
    7 => 'theory of a deadman',
    8 => 'theory of love',
    9 => 'theory meaning',
  ),
)

在 PHP 中转换为对象后，我需要能够访问/找到对象中的“相对论”。

Answer 1

你应该使用https://www.php.net/manual/en/function.json-decode.php

例子：

$myJson = '["theory",["theory","theory of relativity","theory test","theory of everything","theory definition","theory of evolution","theory of mind","theory of a deadman","theory of love","theory meaning"]]';

print_r(json_decode($myJson));

问：如何获取“相对论”？：

答：

$data = json_decode($myJson);
echo $data[1][1];
