PDO :: execute()对我来说是一个未定义的方法？

Question

这是有问题的PDO代码:

$db->prepare("INSERT INTO user (id, name, password, salt, email, join_date, chats)
              VALUES (NULL, ?, ?, ?, ?, ?, ?)");
$db->execute(array($name, $password, $salt, $email, $joindate, ''));

我得到致命的错误:Fatal error: Call to undefined method PDO::execute() in register.php on line 12第12行是上面的执行.可能有什么不对？该数组包含完美的字符串,使用print_r进行检查.

Answer 1

PDO::prepare返回一个PDOStatement具有该execute方法的对象.

$st = $db->prepare(...);
$st->execute(...);
