$db = new PDO('mysql:host=localhost;dbname='.$dbname, $uname, $pwd); 
$db->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_WARNING); 


$query = "SET @sql = NULL; ". 
" SELECT GROUP_CONCAT(DISTINCT CONCAT('MAX(IF(a.Name = ''', ". 
" a.Name, ''', ca.value, NULL)) AS ', a.Name )) INTO @sql ". 
" FROM cust_attribute ca ". 
" INNER JOIN attribute a ON ca.idAttribute = a.idAttribute ". 
" INNER JOIN customer c ON c.idCustomer = ca.idCustomer ". 
" WHERE a.publish = 'Y'; ". 
" SET @sql = CONCAT('SELECT c.idCustomer, c.namaCustomer, ' ". 
" ' c.email, c.noTelp, ', @sql, ' FROM cust_attribute ca', ". 
" ' INNER JOIN attribute a ON ca.idAttribute = a.idAttribute', ". 
" ' INNER JOIN customer c ON c.idCustomer = ca.idCustomer', ". 
" ' GROUP BY c.idCustomer'); ". 
" SELECT @sql; ". 
" prepare stmt FROM @sql; ". 
" execute stmt;"; 

$result_array = array();
$queryku = $db->query($query);
$result_array = $queryku->fetchAll(PDO::FETCH_OBJ);
var_dump($result_array);
?>

Anyone can help me or give me a suggest here??

This issue has come up before with regards to PDO. Not sure if it’s a bug or a security feature (might be related to this: Mysql can't perform more than 1 query at a time).

Have a look at this solution: http://www.php.net/manual/en/book.pdo.php#96264
