MySQLi INSERT出错

Question

我有查询，我再次尝试从pop3帐户传递到mysql数据库：

mysqli_query($con,"INSERT INTO procesa_emails (body_mail, uid_message, fecha, from, to, subject, message_id) VALUES ('".mysqli_real_escape_string($con,htmlentities(str_replace("'","",str_replace('"','',$message))))."','".mysqli_real_escape_string($con,htmlentities($uid_mess))."','".mysqli_real_escape_string($con,htmlentities($fecha))."','".mysqli_real_escape_string($con,htmlentities($from))."','".mysqli_real_escape_string($con,htmlentities($to))."','".mysqli_real_escape_string($con,htmlentities($subject))."','".mysqli_real_escape_string($con,htmlentities($mui))."')")or die(mysqli_error($con));

但它让我回答：

You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'from, to, subject, message_id) 

我尝试使用str_replace（“'”，“”，str_replace（'“'。'''））但它也不起作用

Answer 1

FROM是reserved keyword。因此，如果要在查询中使用它，则需要将其包装在反引号中，如下所示：

mysqli_query($con,"
INSERT INTO procesa_emails (body_mail, uid_message, fecha, `from`, ...

希望这有帮助！
