的foreach循環PHP錯誤

我想環路「textDisplay形式」使用的foreach但林不知道這是我的PHP代碼的部分是錯誤的，它給了我一個「試圖獲得非對象的屬性」錯誤的foreach循環PHP錯誤

    } 
]

}

我的PHP代碼

 
$json = file_get_contents('https://www.googleapis.com/youtube/v3/commentThreads?part=snippet%2Creplies&videoId='.$videoid.'&key='.$apikey); 
$ytdata = json_decode($json); 
foreach($ytdata->items[0]->snippet->topLevelComment->snippet->textDisplay as $hit){ 
    echo $hit; 
}

感謝

$ytdata->items[0]->snippet->topLevelComment->snippet->textDisplay不是數組 - 它是一個字符串。

也許你打算循環的項目？

foreach ($ytdata->items as $item) { 
    echo $item->snippet->topLevelComment->snippet->textDisplay; 
}
