Comment faire une boucle sur le tableau JSON en utilisant PHP

Mon code PHP:

$obj = json_decode($data);
print $obj->{'name'};

Alors qu'il travaille pour les non-tableaux, je ne peux pas pour la vie de me comprendre comment imprimer toutes les valeurs dans les "Commentaires" de la Matrice.

Ce que je voudrais faire est de faire une boucle par cette réponse, probablement avec forreach(), résultant en une liste contenant la notation et l'extrait pour chaque examen dans la réponse.

Toute orientation /orientation est grandement appréciée..

Ci-dessous est le JSON, je travaille avec. (c'est la réponse de l'Yelp API).

  1. 17

    Vous sont probablement de la difficulté à cause des examens est un tableau et que vous tentez d'y accéder comme un objet JSON.

    $obj = json_decode($data, TRUE);
for($i=0; $i<count($obj['reviews']); $i++) {
echo "Rating is " . $obj['reviews'][$i]["rating"] . " and the excerpt is " . $obj['reviews'][$i]["excerpt"] . "<BR>";
}
  2. 1

    Je ne suis pas sûr exactement ce que vous voulez, mais je suppose que vous voulez imprimer seulement pour le débogage de la droite maintenant. Vous pouvez essayer avec print_r($obj); et var_dump($obj); - ils doivent imprimer quelque chose, surtout var_dump().
    Quand vous voyez les données, vous pouvez facilement modifier la fonction un peu, de sorte que vous pouvez faire par exemple print_r($obj->reviews) ou print_r($obj['reviews']), selon si $obj est un objet ou un tableau.

  3. 0

    Vous pouvez utiliser var_dump ou print_r.

    <?php 
$decodedJSON = json_decode($jsonData);
//Put everyting to the screen with var_dump;
var_dump($decodedJSON);
//With print_r ( useful for arrays );
print_r($decodedJSON);
//List just review ratings with foreach;
foreach($decodedJSON['reviews'] as $review){
echo $review['rating'];
}
?>
