How to add key values into decoded json in PHP?

问题

I use youtube gdata to get video links. PHP code I use:

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

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

The url is http://gdata.youtube.com/feeds/api/videos?q=whatever&v=2&max-results=5&format=1&alt=jsonc. This gives me the following output:

Now I want something like below:

The names are indexed array like:

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

How to perform this? I used array_push or merge functions, but it adds only an array, not a variable like Title or Content.

回答1:

Have a counter outside the foreach like $count = 0; then inside the foreach do $count++;. You can then get the name corresponding to the item using $names[$count]; inside the foreach.

$json_output = json_decode($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++;
}
