php - 如何在PHP中将键值添加到解码的json中？

Question

我使用youtube gdata获取视频链接。我使用的PHP代码:

$json_output = json_decode($json,TRUE);
foreach ( $json_output['data']['items'] as $data ){

echo $data['title']
. '</br>' 
. $data['content'][1]
. '</br>';

网址是http://gdata.youtube.com/feeds/api/videos?q=whatever&v=2&max-results=5&format=1&alt=jsonc。这给了我以下输出:

现在我想要以下内容:

名称是索引数组，例如:

Names=Red, Green, You, Me.....

如何执行呢？我使用了array_push或merge函数，但是它仅添加一个数组，而不添加诸如Title或Content之类的变量。

Answer 1

在foreach之外有一个计数器，例如$count = 0;，然后在foreach内有一个$count++;。然后，您可以使用$names[$count];中的foreach获得与该项目相对应的名称。

$json_output = json_decode($json,TRUE);
$count = 0;
$names = ['name1', 'name2', 'name3', 'name4'];
foreach ( $json_output['data']['items'] as $data ){
     echo ($data['title'] . '<br />' . $data['content'][1] . '<br />' . $names[$count] . '<br />');
     $count++;
}
