PHP利用PHPMailer實現郵件傳送功能

<?php
 
// 引入PHPMailer的核心檔案
require_once("PHPMailer/class.phpmailer.php");
require_once("PHPMailer/class.smtp.php");
 
// 範例化PHPMailer核心類
$mail = new PHPMailer();
 
// 是否啟用smtp的debug進行偵錯 開發環境建議開啟 生產環境註釋掉即可 預設關閉debug偵錯模式
$mail->SMTPDebug = 1;
 
// 使用smtp鑑權方式傳送郵件
$mail->isSMTP();
 
// smtp需要鑑權 這個必須是true
$mail->SMTPAuth = true;
 
// 連結qq域名郵箱的伺服器地址
$mail->Host = 'smtp.qq.com';
 
// 設定使用ssl加密方式登入鑑權
$mail->SMTPSecure = 'ssl';
 
// 設定ssl連線smtp伺服器的遠端伺服器埠號
$mail->Port = 465;
 
// 設定傳送的郵件的編碼
$mail->CharSet = 'UTF-8';
 
// 設定發件人暱稱 顯示在收件人郵件的發件人郵箱地址前的發件人姓名
$mail->FromName = '發件人暱稱';
 
// smtp登入的賬號 任意郵箱即可
$mail->Username = 'xxxxxxx@163.com';
 
// smtp登入的密碼 使用生成的授權碼
$mail->Password = '**********';
 
// 設定發件人郵箱地址 同登入賬號
$mail->From = 'xxxxxxx@qq.com';
 
// 郵件正文是否為html編碼 注意此處是一個方法
$mail->isHTML(true);
 
// 設定收件人郵箱地址
$mail->addAddress('xxxxxxxxx@qq.com');
 
// 新增多個收件人 則多次呼叫方法即可
$mail->addAddress('xxxxxxxxx@163.com');
 
// 新增該郵件的主題
$mail->Subject = '郵件主題';
 
// 新增郵件正文
$mail->Body = '<h1>Hello, i am autofelix</h1>';
 
// 為該郵件新增附件
$mail->addAttachment('./附件.pdf');
 
// 傳送郵件 返回狀態
$status = $mail->send();
