我似乎无法从PDO收到任何错误消息:

#$dbh->setAttribute( PDO::ATTR_ERRMODE, PDO::ERRMODE_WARNING );
try {
  $sth = $dbh->prepare('@$%T$!!!');
  print_r($sth);
  print_r($dbh->errorInfo());
} catch (PDOException $e) {
    echo $e->getMessage();
}

它只给出:

PDOStatement Object
(
    [queryString] => @$%T$!!!
)
Array
(
    [0] => 00000
    [1] =>
    [2] =>
)

setAttribute没有任何帮助.

这是PHP 5.3.3
支持MySQL的Apache 2.0 Handler PDO驱动程序
客户端API版本mysqlnd 5.0.7-dev - 091210 - $ Revision:300533 $

我该怎么做才能获得错误信息？

这是我的PHP sql语句,它在var转储时返回false

$password_md5 = md5($_GET['password']);
$sql = $dbh->prepare('INSERT INTO users(full_name, e_mail, username, password, password_plain) VALUES (:fullname, :email, :username, :password, :password_plain)');
$result = $sql->execute(array(
                    ':fullname' => $_GET['fullname'], 
                    ':email' => $_GET['email'], 
                    ':username' => $_GET['username'],
                    ':password' => $password_md5,
                    ':password_plain' => $_GET['password']));
