我想环路“textDisplay形式”使用的foreach但林不知道这是我的PHP代码的部分是错误的,它给了我一个“试图获得非对象的属性”错误的foreach循环PHP错误

}

我的PHP代码

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

感谢

$ytdata->items[0]->snippet->topLevelComment->snippet->textDisplay不是数组 - 它是一个字符串。

也许你打算循环的项目?

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