Answer 1

리뷰가 배열이고 JSON 객체로 액세스하려고하므로 문제가 발생했을 수 있습니다.

$obj = json_decode($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>"; 
} 

Answer 2

정확하게 원하는 것은 무엇인지 모르겠지만 바로 지금 디버깅 용으로 인쇄하고 싶습니다. print_r($obj);과 var_dump($obj);으로 시도해 볼 수 있습니다. 무엇인가를 인쇄해야합니다. 특히 var_dump()입니다. 데이터가 표시되면 기능을 쉽게 편집 할 수 있으므로 $obj이 객체인지 배열인지에 따라 인스턴스가 print_r($obj->reviews) 또는 print_r($obj['reviews']) 일 수 있습니다.

Answer 3

var_dump 또는 print_r을 사용할 수 있습니다.

<?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']; 
} 
?>
