php 如何解码一组 json 对象

How to decode an array of json objects

提问by Byron Whitlock

I have an array of json objects like so:

我有一个像这样的json对象数组：

[{"a":"b"},{"c":"d"},{"e":"f"}]

[{"a":"b"},{"c":"d"},{"e":"f"}]

What is the best way to turn this into a php array?

将其转换为 php 数组的最佳方法是什么？

json_decodewill not handle the array part and returns NULLfor this string.

json_decode不会处理数组部分并返回NULL此字符串。

json_decode() does so work. The second param turns the result in to an array:

json_decode() 确实如此。第二个参数将结果转换为数组：

var_dump(json_decode('[{"a":"b"},{"c":"d"},{"e":"f"}]', true));

// gives

array(3) {
  [0]=>
  array(1) {
    ["a"]=>
    string(1) "b"
  }
  [1]=>
  array(1) {
    ["c"]=>
    string(1) "d"
  }
  [2]=>
  array(1) {
    ["e"]=>
    string(1) "f"
  }
}

$array = '[{"a":"b"},{"c":"d"},{"e":"f"}]';
print_r(json_decode($array, true));

Read the manual - parameters for the json_decodemethod are clearly defined: http://www.php.net/manual/en/function.json-decode.php

阅读手册 -json_decode明确定义了该方法的参数：http: //www.php.net/manual/en/function.json-decode.php
