Verwenden Sie rowCount();
Versuchen Sie im Inneren, die Anzahl der betroffenen Zeilen durch Ihre SQL-Anweisung zu überprüfen
try {
$dbh = new PDO("mysql:host=$hostname;dbname=$dbname", $username, $password);
/* * * echo a message saying we have connected ** */
//echo 'Connected to database<br />';
$sql = "DELETE FROM ukgh WHERE telephone = :telephone";
$stmt = $dbh->prepare($sql);
$stmt->bindParam(':telephone', $telephone, PDO::PARAM_STR);
$stmt->execute();
$count = $stmt->rowCount();// check affected rows using rowCount
if ($count > 0) {
echo 'Success - The record for ' . $telephone . ' has been deleted.';
} else {
echo "Your error message";
}
} catch (PDOException $e) {
echo $e->getMessage();
}
