access json object and array

Question

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"]
 }]
}

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

Like: prod_ingredient or prod_danger.

I have tried:

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

and

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

• Gumbo: Use var_dump, var_export or print_r to see how the return value looks like.

Answer 1

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'];

• menardmam: this code : $json = file_get_contents('produits-lemieux.com/json.txt'); $prod = json_decode($json); $prod_ingredient = $prod['Liste_des_produits1'][0]['prod_ingredient']; print_r($prod_ingredient); result in this error = Fatal error: Cannot use object of type stdClass as array in /home/studiot/public_html/test3.php on line 12
• Alex Barrett: My apologies marc-andre mendard, I should have checked the documentation before answering. I have revised my answer slightly.
• menardmam: just adding TRUE make the whole thng different... can you explain more, but it work, your rock !
• Alex Barrett: Passing true to json_encode() decodes JSON objects as associative arrays rather than PHP objects. I was under the impression this was the default behaviour, and it is more intuitive IMO. In any case, the manual page I linked to explains everything in detail.

Answer 2

Use json_decode

Then you can access the data as a regular array.
