Get attribute code from attribute value

Question

Suppose color and price and manufacturer are three attribute codes.

black and blue are attribute values for color.
$0-100 and &101-200 are attribute values for price.
hp and dell are attribute values for price.

On category page, in filter section if I'm selecting attribute values black and &101-200. How can I get corresponding attribute codes?

In filter.phtml file sing this code I'm getting selected attribute code but not the attribute value in a proper format.

    <?php
$appliedFilters = Mage::getSingleton('catalog/layer')->getState()->getFilters();
foreach ($appliedFilters as $item) {
      $items[] = $item->getFilter()->getRequestVar();

} 
foreach ($items as $item) {
     echo ($item."<br>");
   }

Answer 1

Try this:

$appliedFilters = Mage::getSingleton('catalog/layer')->getState()->getFilters();

foreach ($appliedFilters as $item):

   $filter = $item->getFilter();
   $items[] = array(
     'code'    => $filter->getRequestVar(),
     'label'   => $item->getName(),
     'value'   => $item->getLabel()
   );

endforeach;
