Default Multidimensional Array help

Hi :)


I am creating an XML file out of a mysql query with nested arrays.
Currently I can get 1 element and 1 child with a properly formatted XML file with the below script .


My question is: How do I add 3 to 4 more child elements to the below 'playlist' array ?
Currently ,I have one parent 'Artist' and one child 'english' ...
I need to add more child elements to the 'Artist' array like urlPath, spanish, biography, etc

My addled thoughts...
So, would the multidimensional array be like:
$playlist[ [$artist [ ] ] [$media[ ] ] [$mediaElement] ] ?

for the 'trackName' child:
$playlist [ "Artist 1" ] [ "Track 1" ] [ "trackName" ]
or for 'urlPath' child :
$playlist [ "Artist 1" ] [ "Track 1" ] [ "urlPath" ]


Do I have to add another dimension to the 'playlist' array? Do I need another foreach loop ?
Is there an easier more efficient way to do this?
Be nice to spell out the schema in some way in the script...in case you need to add more levels...like a 'subCategory'

I am a bit new to this so any help would be greatly appretiated .... head is spinning a bit

<?php
@ $db = mysql_connect('127.0.0.1','name','pass');

    if (!$db)
    {
    echo 'Error:Could Not Connect';
    exit;
    }

    mysql_select_db('univision');


$sql = 'SELECT artist.artist_name, media.english, media.path ';
$sql .= 'FROM media, artist ';
$sql .= 'WHERE artist.artist_id = media.artist_id LIMIT 0, 30 ';

$result = mysql_query($sql);
while ($row = mysql_fetch_array($result))
{
$playlist[$row['artist_name']] [] = $row['english'];
//would like to add more children here...
}

$xml = "<sirenreels>\n";

foreach ($playlist as $artist => $media)
{
$num_media = count($media);
       $xml .= "<artist>\n";

       $xml .= "\t<meta>\n";
       $xml .= "\t\t<title>".$artist."</title>\n";
    $xml .= "\t</meta>\n";

    $xml .= "\t<content>\n";

foreach ($media as $mediaVal)
{
            $xml .= "\t\t<media>\n";
            $xml .= "\t\t\t<english_name>".$mediaVal."</english_name>\n";
            ///add more children
            ///add more children
            $xml .= "\t\t</media>\n";

}

    $xml .= "\t</content>\n";
    $xml .= "</artist>\n";
}
$xml .= "</sirenreels>\n";
print $xml
