PHPMailer - A full-featured email creation and transfer class for PHP。

在PHP環境中可以使用PHPMailer來建立和傳送郵件。

最新版本(20181012)是PHPMailer 6.0.5，這個無法相容php5.5以下的環境。由於我需要維護 php5.3的專案，需要切換到PHPMailer5.2來發送郵件。

基本使用

下載解壓後。新建一個測試demo。

<?php
require 'PHPMailerAutoload.php';

$mail = new PHPMailer;

$mail->SMTPDebug = 3;                               // Enable verbose debug output

$mail->isSMTP();                                      // Set mailer to use SMTP
$mail->Host = 'smtp.exmail.qq.com';  // Specify main and backup SMTP servers
$mail->SMTPAuth = true;                               // Enable SMTP authentication
$mail->Username = '
 
[email protected]';                 // SMTP username
$mail->Password = 'yourpassword';                           // SMTP password
$mail->SMTPSecure = 'ssl';                            // Enable TLS encryption, `ssl` also accepted
$mail->Port = 465;                                    // TCP port to connect to

$mail->setFrom('
 
[email protected]', 'Mailer');
$mail->addAddress('[email protected]', 'Ryan Miao');     // Add a recipient
$mail->addAddress('[email protected]');               // Name is optional
// $mail->addReplyTo('[email protected]', 'Information');
$mail->addCC('[email protected]');
$mail->addBCC('
 
[email protected]');

$mail->addAttachment('/var/tmp/file.tar.gz');         // Add attachments
$mail->addAttachment('/tmp/image.jpg', 'new.jpg');    // Optional name
$mail->isHTML(true);                                  // Set email format to HTML

$mail->Subject = 'Here is the subject';
$mail->Body    = 'This is the HTML message body <b>in bold!</b>';
$mail->AltBody = 'This is the body in plain text for non-HTML mail clients';

if(!$mail->send()) {
    echo 'Message could not be sent.';
    echo 'Mailer Error: ' . $mail->ErrorInfo;
} else {
    echo 'Message has been sent';
}

開啟SMTPDebug可以檢視日誌

 `0` No output
 `1` Commands
 `2` Data and commands
 `3` As 2 plus connection status
 `4` Low-level data output

錯誤資訊儲存在 $mail->ErrorInfo物件中。

儲存為mail.php, 命令列執行

php mail.php

即可看到日誌，以及郵件傳送成功。
