Question

How to call all the tags at once?

I curently do something like this:

$artist['tags']['0']['name'];
$artist['tags']['1']['name'];
// and so on for all 5 (0-4)


[tags] => Array
        (
            [0] => Array
                (
                    [name] => hip-hop
                    [url] => http://www.last.fm/tag/hip-hop
                )

            [1] => Array
                (
                    [name] => romanian
                    [url] => http://www.last.fm/tag/romanian
                )

            [2] => Array
                (
                    [name] => romanian hip-hop
                    [url] => http://www.last.fm/tag/romanian%20hip-hop
                )

            [3] => Array
                (
                    [name] => rap
                    [url] => http://www.last.fm/tag/rap
                )

            [4] => Array
                (
                    [name] => hip hop
                    [url] => http://www.last.fm/tag/hip%20hop
                )

        )

You can use a foreach loop to iterate through all the tags of an artist:

$tags = array();
foreach ($artist['tags'] as $tag)
{
   $tags[] = $tag['name'];
}
echo implode(', ', $tags);
