title: Array Serialization Issue
body: <p>I'm storing some information which has been serialized by using jQuery into a MySQL database :</p>
  
  <pre><code>$(function () {
      $("#sortable").sortable({
          stop: function (event, ui) {
              $("#q35list").val($(this).sortable('serialize'));
          }
      });
      $("#sortable").disableSelection();
  </code></pre>
  
  <p>This stores the relevant information in the DB fine (via a .php save page).</p>
  
  <p>However, when I return it and unserialize it using the following:</p>
  
  <pre><code>$arr = unserialize($results['q35list']);
  if(!$arr) $arr=array();
  var_dump($arr);
  </code></pre>
  
  <p>It' not an array! It's as follows:</p>
  
  <pre><code>string(55) "Set[]=2&amp;Set[]=1&amp;Set[]=3&amp;Set[]=4&amp;Set[]=5&amp;Set[]=6&amp;Set[]=7"
  </code></pre>
  
  <p>I am now at the point where I cannot see the wood from the trees...</p>
