[SOLVED] Double(+=) arrow in arrays?

[Qaaolchoura]

Hello, sorry if this is idiotic, but I couldn't find the answer either elsewhere.

Is there a way to include a double (or more) arrow in an array, without using subarrays?

 

For example, if I had a set of information about music that I wanted to export as xml (as I did for an experiment).

 

</php
<-- create document, header, etc-->

$dataArray = array("Graceland" => "Paul Simon" => "Rock", "Days of Future Passed" => "Moody Blues" => "Rock");

foreach($dataArray as $nameArr => $artistArr => $genreArr)
{
//create data for name
$name = $dom->createElement('name');
$nameText = $dom->createTextNode($nameArr);
$name->appendChild($nameText);

<--repeat for $artist & $genre-->

// create node for album and add data as child
$album = $dom->createElement('album');
$album->appendChild($name);
$album->appendChild($artist);
$album->appendChild($genre);
}

<--output xml-->
?>

I get an error because of the unexpected double arrow.

 

Ultimately I'd want to draw this from a mySQL database rather than using static arrays, but I'm still wondering if there's a way to do this.  It seems like it'd be useful if I wanted to pass arrays from one php file to another.

 

Thanks,

no there is not. I don't even know what you are trying to accomplish with more than 1 =>. Just use a multi-dimensional array.

I assume by double arrow you mean this

foreach($dataArray as $nameArr => $artistArr => $genreArr)

No this is not possible. You'll have to use a subarray. Whats wrong with using a sub array?

It seemed like it'd be easier for me to handle for small datasets than a subarray, but yeah, when I say it I realize that's a bad reason.

 

Any rate, thanks
