Question

我有json，我想删除它的第一个属性，但不知道如何。这是我的json：

["car",["Nissan","Chevrolet","Ford"]]

我想这样表现出来：

["Nissan","Chevrolet","Ford"]

我的Php

$url = 'http://example.com/json?=car';
$content = file_get_contents($url);
echo $content;

Answer 1

看起来你想要提取数组。

json_decode($content[1])

Answer 2

首先需要将其转换为数组，将其指向您想要的特定索引然后再次编码。（假设你问题上的json字符串确实是你所拥有的json字符串）。

$contents = '["car",["Nissan","Chevrolet","Ford"]]';
$data = json_decode($contents, true);
$contents = json_encode($data[1]);
echo $contents; // ["Nissan","Chevrolet","Ford"]

Answer 3

$json_array = json_decode(file_get_contents($url)); //converts json data to array

echo $json_array[1]; //displays ["Nissan","Chevrolet","Ford"]

//contents of json_array
 /* Array
  (
    [0] => car
    [1] => Array
      (
        [0] => Nissan
        [1] => Chevrolet
        [2] => Ford
    )

  ) */
