How to parse Hypertable data using php - hypertable

Question

I have inserted data's in Hypertable. But i don't know, how to get particular value from result. My PHP thrift code is :
$GLOBALS['THRIFT_ROOT'] = "/opt/hypertable/0.9.5.6/lib/php";
require_once $GLOBALS['THRIFT_ROOT'].'/ThriftClient.php';
$client = new Hypertable_ThriftClient("localhost", 38080);
$namespace = $client->namespace_open("appuniv");
$query = "select * from category_details limit 1";
$tab = $client->hql_query($namespace, $query);
var_dump($tab);
I'm getting the below result :
object(Hypertable_ThriftGen_HqlResult)#24 (4) { ["results"]=> NULL
["cells"]=> array(2) { [0]=> object(Hypertable_ThriftGen_Cell)#25 (2)
{ ["key"]=> object(Hypertable_ThriftGen_Key)#26 (6) { ["row"]=>
string(32) "077262cc53a1fb1b5f651d31b6bf81ba" ["column_family"]=>
string(8) "category" ["column_qualifier"]=> string(4) "name"
["timestamp"]=> float(1.3419935154984E+18) ["revision"]=>
float(1.3419935154984E+18) ["flag"]=> int(255) } ["value"]=> string(7)
"Medical" } [1]=> object(Hypertable_ThriftGen_Cell)#27 (2) { ["key"]=>
object(Hypertable_ThriftGen_Key)#28 (6) { ["row"]=> string(32)
"077262cc53a1fb1b5f651d31b6bf81ba" ["column_family"]=> string(8)
"category" ["column_qualifier"]=> string(4) "type" ["timestamp"]=>
float(1.3419935154984E+18) ["revision"]=> float(1.3419935154984E+18)
["flag"]=> int(255) } ["value"]=> string(7) "android" } }
["scanner"]=> NULL ["mutator"]=> NULL } 0.9678
May i know how to get the ["value"]=> string(7) "Medical" value from above result.

/**
* Sort result by column family/qualifier
* #param thrift result
*/
private function sort($data)
{
$result = array();
foreach ($data as $cell)
{
$row = $cell->key->row;
if (!isset($result[$row])) {
$result[$row] = new stdClass;
$result[$row]->row = $cell->key->row;
foreach ($this->columns as $col) {
$pos = strpos($col, ':') ;
$qualifier = ($pos) ? substr($col, $pos + 1) : NULL;
$col = !$pos ? $col : substr($col, 0, $pos);
if (!$qualifier)
$result[$row]->{$col} = NULL;
else if ($qualifier[0] != '/')
$result[$row]->{$col}[$qualifier] = NULL;
}
}
$result[$row]->{$cell->key->column_family}[$cell->key->column_qualifier] = $cell->value;
}
return $result;
}
