访问json对象和数组

Question

这是我的JSON数据:

{"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法是什么？

喜欢:prod_ingredient或prod_danger.

我试过了:

$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

Answer 1

使用json_decode将数据转换为关联数组.

$data = json_decode($jsonString, true);

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