[RESOLVED] Variable variables question

[ClarkF1]

I have the following code:

$gettracks = $$value['recenttracks'][0]['track'];

foreach($gettracks as $songs)
    {
      extract($songs);
      $time = strtotime($date);
      $tracks[] = array($time,$artist,$name,$url,$value);
    }

Does anyone know why it throws up the error:
"Fatal error: Cannot use string offset as an array"

I can get round it using:

foreach ($$value as $value2)
    {
      $gettracks = $value2[0]['track'];
    }

foreach($gettracks as $songs)
{
  extract($songs);
  $time = strtotime($date);
  $tracks[] = array($time,$artist,$name,$url,$value);
}

Just curious......

Aha, it was an empty array causing the problem.
