这是因为'$ JSON_OBJECT [ '项']'是一个数组，而不是一个结构。尝试遍历它，或者只是看到第一个条目：'$ json_object ['items'] [0]' - 同样'description'位于'snippet'内，而不是位于项目根目录。 – wiesion

尝试以下代码：

<?php 
$unparsed_json = file_get_contents("https://www.googleapis.com/youtube/v3/videos?id=7lcdeyxw3mm&key=aizasyb-3ayh1i6mlxxqwcr-ndj07tepfalklfs&part=snippet,contentdetails,statistics,status"); 
$json_object = json_decode($unparsed_json, true); 
?> 

<html> 
    <head> 
     <title>music player</title> 
     <link rel="stylesheet" href="/resources/app.css"> 
    </head> 
    <body> 
     <p><?php echo $json_object['items'][0]['snippet']['localized']['description']; ?></p> 
    </body> 
</html>
