Question

获取以下错误 ...以非pdo 格式运行良好：

解析错误：语法错误，意外''（T_ENCAPSED_AND_WHITESPACE），期待标识符（T_STRING）或变量（T_VARIABLE）或数字（T_NUM_STRING）

// update user's current ip and current login date in db (prepared not required as no user input)
$db->exec("UPDATE test_users SET currIP = $_SERVER['REMOTE_ADDR'], dtCurrLogin = UTC_TIMESTAMP() WHERE user = $user");

将数组索引调用更改为：

$db->exec("UPDATE test_users 
    SET currIP = '" . $_SERVER['REMOTE_ADDR'] . "', 
        dtCurrLogin = UTC_TIMESTAMP() 
    WHERE user = $user");

我仍然建议使用prepare来电。

$stm = $db->prepare("UPDATE test_users 
        SET currIP = :ip, 
            dtCurrLogin = UTC_TIMESTAMP() 
        WHERE user = :usr");
$stm->bindParam( ':ip', $_SERVER['REMOTE_ADDR'], PDO::PARAM_STR );
$stm->bindParam( ':usr', $user, PDO::PARAM_INT );
$stm->execute();

pdo exec更新语句出错？
