錯誤與庫MySQLi INSERT

Question

我有部份查詢，再次聲明，我試圖通過從POP3帳戶mysql數據庫：

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)); 

但它返回我：

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) 

我試着用str_replace函數（ 「'」，「」，str_replace（'''。''））但是它也行不通

Answer 1

FROM是一個reserved keyword所以，如果你想在你的查詢中使用它，你需要包裝它在反引號中，像這樣：

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

希望這會有所幫助！
