使用 PDO 和 MySQL 更新查询
我试图用PDO编写更新查询,只有我无法让我的代码执行?
try {
$conn = new PDO("mysql:host=$hostdb; dbname=$namedb", $userdb, $passdb);
$conn->exec("SET CHARACTER SET utf8"); // Sets encoding UTF-8
$conn->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
$sql = "UPDATE `access_users`
(`contact_first_name`,`contact_surname`,`contact_email`,`telephone`)
VALUES (:firstname, :surname, :telephone, :email);
";
$statement = $conn->prepare($sql);
$statement->bindValue(":firstname", $firstname);
$statement->bindValue(":surname", $surname);
$statement->bindValue(":telephone", $telephone);
$statement->bindValue(":email", $email);
$count = $statement->execute();
$conn = null; // Disconnect
}
catch(PDOException $e) {
echo $e->getMessage();
}
