How would you do this php code?
<p>Is there a better way to write the below, other then using a switch or if/else statement?  Like is this a situation where a PHP's varaiable variable ( $$var ) could come to use?
If so how would you write this code?</p>

<pre><code>$type = 2;

switch ($type) {
 case 1:
   $type = 'gif';
   break;
 case 2:
   $type = 'jpg';
   break;
 case 3:
   $type = 'png';
   break;
 default:
   $type = 'jpg';
   break;
}
</code></pre>
