How to remove the word "delete" in the guestbook when refreshing the page?

Question

PHP

There is this code:

/* Удаление записи из БД */
if(isset($_GET['id']) && isset($_GET['del'])){
    echo  'Удаление';

    $query_del ="DELETE FROM msgs WHERE id = ".(int)$_GET['del'];

    mysqli_query($link, $query_del);
}

Further in the while loop there is a link:

echo '<a href="' . 'http://mysite.local/index.php?id=gbook&del=' .$row['id'] . '">Удалить</a>';

When deleting a certain entry from the guest book, the word "Deletion" appears, and in the address bar a line like this: mysite.local/index.php?id=gbook&del=25
It is necessary that the word "Deletion" disappear when the page is refreshed.
