访问json对象和数组 [英] access json object and array

问题描述

这是我的JSON数据:

Here is my JSON data :

{
  "Liste_des_produits1": [{
    "Added_Time": "28-Sep-2009 16:35:03",
    "prod_ingredient": "sgsdgds",
    "prod_danger": ["sans danger pour xyz"],
    "prod_odeur": ["Orange"],
    "prod_nom": "ceciestunproduit",
    "prod_certification": ["HE • Haute Efficité", "Certifier Ecologo", "Contenant recyclable"],
    "prod_photo": "",
    "prod_categorie": ["Corporel"],
    "prod_desc": "gdsg",
    "prod_format": ["10 kg", "20 kg"]
  }, {
    "Added_Time": "28-Sep-2009 16:34:52",
    "prod_ingredient": "dsgdsgdsf",
    "prod_danger": ["Sans danger pour le fausse sceptiques"],
    "prod_odeur": ["Agrumes", "Canneberge"],
    "prod_nom": "jsute un test",
    "prod_certification": ["100% Éco-technologie", "Certifier Ecologo", "Contenant recyclable"],
    "prod_photo": "",
    "prod_categorie": ["Corporel"],
    "prod_desc": "gsdgsdgsdg",
    "prod_format": ["1 Litre", "10 kg"]
  }]
}

在PHP中，访问不同数据值的方式是什么?

In PHP, what is the way to access different values of data?

例如:prod_ingredient或prod_danger.

我尝试过:

$prod = $result->{'Liste_des_produits1'};
print_r($prod[0]); // error

和

$result = json_decode($json);
print_r($result['Liste_des_produits1'].prod_ingredient[1]); // error

推荐答案

使用 json_decode 将数据转换为关联数组.

Use json_decode to convert the data to an associative array.

$data = json_decode($jsonString, true);

// extend this concept to access other values
$prod_ingredient = $prod['Liste_des_produits1'][0]['prod_ingredient'];
