Question

任何人都可以告诉我如何使用php从下面的数组中提取'honda'值吗？

{
        "version": "1.0",
        "encoding": "UTF-8",
        "entry": {
            "name": "bob",
            "car": {
                "model": "honda"
            }
        }
    }

Answer 1

这看起来像一个json编码对象。你能做的是：

$info = json_decode($data, true); //where $data has your stuff from the question
$carModel = $obj['entry']['car']['model'];

Answer 2

如果你在名为“obj”的变量中拥有所有这些，那么

$obj = '{ "version": "1.0", "encoding": "UTF-8", "entry": { "name": "bob", "car": { "model": "honda" } } }';     
$arr = json_decode($obj, true);
echo $arr['entry']['car']['model'];

应该是'honda'

EDITED：Per Omar下面，你需要将true作为json_decode中的第二个参数。他应该被选为正确的答案。

Answer 3

使用json_decode：http://php.net/manual/fr/function.json-decode.php

<?php

$json = '{"version": "1.0","encoding": "UTF-8","entry": {"name": "bob","car": {"model": "honda"} } }';

$tab = json_decode($json, true);

$honda = $tab['entry']['car']['model'];

var_dump($honda);


// or with object:


$obj = json_decode($json);

$honda = $obj->entry->car->model;

var_dump($honda);
