我正在用mysql創建一個登錄和註冊表單，當我提交給用戶時，我需要給他發送一封在他註冊郵箱中的收件箱的激活碼，但是當我在註冊表格中提交時，這個錯誤：未定義的變量：C：\ wamp \ www中的INFO \ line 87上的new loginregi \ register.php註冊問題php mysql
和此錯誤： 警告：mail（）：無法連接到「本地主機」端口25上的郵件服務器，請在php.ini中驗證您的「SMTP」和「smtp_port」設置，或在第87行的C：\ wamp \ www \ new loginregi \ register.php中使用ini_set（）。
任何人都可以幫助我解決這些錯誤我需要明天修復它非常重要
這是其中的代碼：
register.php<?php
//allow sessions to be passed so we can see if the user is logged in
ob_start();
if(isset($_SESSION)){
session_start();
}
//connect to the database so we can check, edit, or insert data to our users table
$con = mysql_connect('localhost', 'root', '') or die(mysql_error());
$db = mysql_select_db('loginTut', $con) or die(mysql_error());
//include out functions file giving us access to the protect() function
include "./functions.php";

您需要正確配置WAMP設置或發送郵件將無法正常工作。 – 2013-03-02 19:41:37
[**請不要在新代碼中使用'mysql_ *'函數**]（http://bit.ly/phpmsql）。他們不再被維護[並被正式棄用]（https://wiki.php.net/rfc/mysql_deprecation）。看到[**紅框**]（http://j.mp/Te9zIL）？學習[*準備的語句*]（http://j.mp/T9hLWi），並使用[PDO]（http://php.net/pdo）或[MySQLi]（http://php.net/ mysqli） - [這篇文章]（http://j.mp/QEx8IB）將幫助你決定哪個。如果你選擇PDO，[這裏是一個很好的教程]（http://j.mp/PoWehJ）。 – 2013-03-02 19:45:49
@ middaparka第一先生，如果他們是爲你提供信息，因爲你熟悉PHP，但IAM新，我想學習它，但如果Web開發人員像你一樣，我後悔這種選擇第二，如果我發現錯誤，並知道如何修復它我會在這裏閱讀您的評論感謝您的評論 – 2013-03-02 19:48:01
