note 86060 added to function.parse-url

I need to parse out the query string from the referrer, so I created this function.

function parse_query($val)
 {
  /** 
   *  Use this function to parse out the query array element from
   *  the output of parse_url().
   */
  $var  = html_entity_decode($var);
  $var  = explode('&', $var);
  $arr  = array();

  foreach($var as $val)
   {
    $x          = explode('=', $val);
    $arr[$x[0]] = $x[1];
   }
  unset($val, $x, $var);
  return $arr;
 }
