cURL로 생성 된 XML 파일을 JSON으로 변환

Question

boardgamegeek.com XML API을 사용하여 게임에 대한 정보를 얻습니다. 이 URL을 검색하는 데 cURL을 사용할 수 있지만 이제는 XML 데이터를 가지고있어 아무 것도 할 수없는 것 같습니다.

이 내 컬 코드 :

<?php 
header('Content-type: text/xml'); 

$id = 226910; 
$exp = 1; 

$url = 'https://www.boardgamegeek.com/xmlapi/' . (!$exp ? 'boardgame' : 'boardgameexpansion') . '/' . $id . '/'; 

$ch = curl_init(); 
curl_setopt($ch, CURLOPT_URL, $url); 

$xml = curl_exec($ch); 
if ($xml == false) 
{ 
    echo curl_error($ch); 
} 
curl_close($ch); 

그리고 이것은 내 생성 된 출력입니다 : 내가 JSON 배열을 시도하고 생성하기 위해 다음에 내 코드를 변경

을 시도 :

<?php 
// header('Content-type: text/xml'); 

$id = 226910; 
$exp = 1; 

$url = 'https://www.boardgamegeek.com/xmlapi/' . (!$exp ? 'boardgame' : 'boardgameexpansion') . '/' . $id . '/'; 

$ch = curl_init(); 
curl_setopt($ch, CURLOPT_URL, $url); 

$response = curl_exec($ch); 
if ($response == false) 
{ 
    echo curl_error($ch); 
} 
curl_close($ch); 

$xml = simplexml_load_string($response); 
$json = json_encode($xml); 
$array = json_decode($json, true); 

var_dump($array); 

하지만 다음과 같은 오류가 발생합니다.

Answer 1

당신은 옵션 CURLOPT_RETURNTRANSFER 설정하는 것을 잊었다 :이 할당 한 후이 옵션을 사용하지 않으면

curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); 

TRUE to return the transfer as a string of the return value of curl_exec() instead of outputting it out directly (source).

을 $response = curl_exec($ch);이면 $response 변수는 부울 값 true을 포함합니다.

Warning: simplexml_load_string(): Entity: line 1: parser error : Start tag expected, '<' not found

하는 유효한 XML 헤더 사용 보내려면 : 다음 코드 $xml = simplexml_load_string($response);를 실행 한 후 오류 얻을 잘 설명 downvote에 대한

curl_setopt($ch, CURLOPT_HTTPHEADER, ["Content-Type: text/xml"]);
