Question

YouTube에서 검색하고 비디오 비디오 ID 및 제목을 가져 오려고합니다. 나는 "유튜브"를 검색하고있는 울부 짖는 예에서

: 여기

<?php 
    $url="http://gdata.youtube.com/feeds/api/videos?q='youtube'&format=5&max-results=2&v=2&alt=jsonc"; 
    $json = file_get_contents($url,0,null,null); 
    $json_output = json_decode($json); 
    echo '<pre>'; 
     print_r("query results:"); 
     print_r($json_output); 
    '</pre>'; 
    foreach ($json_output->data as $data){ 
    echo "{$data->id}"; 
    echo "{$data->title}"; 
    } 
    ?>

임 [ID]를 밖으로 반향을 시도하고 [ 표제]. 내가 뭘 잘못하고 있는거야?

감사합니다.

이

$items = $json -> data -> items; 

그래서 지금 foreach을 시도하십시오 : 첫번째 itemsObjects Array int로서

Answer 1

변경 라인 9 :

foreach ($json_output->data->items as $data){ 

Answer 2

당신은 가야

foreach ($items as $item){ 
    echo "{$item->id}"; 
    echo "{$item->title}"; 
} 

을 내가 지금 분명 희망한다.
