我正在使用 mysql 创建登录和注册表单，当他提交时我需要用户我在他的注册电子邮件中向他发送收件箱的激活码但是当我在注册表单中提交时我收到此错误：未定义的变量：INFO在第 87 行的 C:\wamp\www\new loginregi\register.php
这个错误：警告：邮件（）：无法在“localhost”端口 25 连接到邮件服务器，验证 php.ini 中的“SMTP”和“smtp_port”设置或在 C:\wamp\www\new 中使用 ini_set()第 87 行的 loginregi\register.php。
谁能帮我修复这些错误我需要在明天之前修复它非常重要
这是以下代码：

<?php
//allow sessions to be passed so we can see if the user is logged in
ob_start();
if(isset($_SESSION)){

$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";
