if(isset( $_GET['DelID'])){
$query = "DELETE FROM toyota WHERE ID = ".$_GET['DelID']." LIMIT 1";
mysqli_query($dbc,$query);
}
/ /Find all records and display them in the following table (if the above deletion code is executed, this is equivalent to refreshing the page)

$data = mysqli_query($dbc,$query);
//Count the number of queried records
$count = mysqli_num_rows($data);
?>
