我想得到“找不到车！”此代码中的消息。请帮帮我。。。如何获取此消息？

<?php 
//Query for Listing count
$brand=$_POST['brand'];
$fueltype=$_POST['fueltype'];
$sql = "SELECT id from tblvehicles where tblvehicles.VehiclesBrand=:brand and tblvehicles.FuelType=:fueltype";
$query = $dbh -> prepare($sql);
$query -> bindParam(':brand',$brand, PDO::PARAM_STR);
$query -> bindParam(':fueltype',$fueltype, PDO::PARAM_STR);
$query->execute();
$results=$query->fetchAll(PDO::FETCH_OBJ);
$cnt=$query->rowCount();
?>
<p><span><?php echo htmlentities($cnt);?> Listings</span></p>
</div>
</div>

在哪里编写echo以获取此消息？

$sql = "SELECT tblvehicles.*,tblbrands.BrandName,tblbrands.id as bid  from tblvehicles join tblbrands on tblbrands.id=tblvehicles.VehiclesBrand where tblvehicles.VehiclesBrand=:brand and tblvehicles.FuelType=:fueltype";
$query = $dbh -> prepare($sql);
$query -> bindParam(':brand',$brand, PDO::PARAM_STR);
$query -> bindParam(':fueltype',$fueltype, PDO::PARAM_STR);
$query->execute();
$results=$query->fetchAll(PDO::FETCH_OBJ);
$cnt=1;
if($query->rowCount() > 0)
{
foreach($results as $result)
{  ?>
