PHPMailer功能強大，使用起來也簡單，所以得到了非常多開發者的喜愛。這里icech就簡單介紹一下PHPMailer發送郵件的實例代碼，為初次使用PHPMailer的朋友提供一個小教程。

1、下載PHPMailer

下載地址：https://github.com/Synchro/PHPMailer

2、將下載的zip文件解壓，找到三個文件：

class.phpmailer.php
class.pop3.php
class.smtp.php

3、代碼實例：mail.php

注意：將mail.php與前面三個類文件放在同一目錄下。

<?php
require 'class.phpmailer.php';

$mail = new PHPMailer;

$mail->IsSMTP();                                      // Set mailer to use SMTP
$mail->Host = 'smtp1.example.com;smtp2.example.com';  // Specify main and backup server
$mail->SMTPAuth = true;                               // Enable SMTP authentication
$mail->Username = 'jswan';                            // SMTP username
$mail->Password = 'secret';                           // SMTP password
$mail->SMTPSecure = 'tls';                            // Enable encryption, 'ssl' also accepted

$mail->From = 'from@example.com';
$mail->FromName = 'Mailer';
$mail->AddAddress('josh@example.net', 'Josh Adams');  // Add a recipient
$mail->AddAddress('ellen@example.com');               // Name is optional
$mail->AddReplyTo('info@example.com', 'Information');
$mail->AddCC('cc@example.com');
$mail->AddBCC('bcc@example.com');

$mail->WordWrap = 50;                                 // Set word wrap to 50 characters
$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;
   exit;
}

echo 'Message has been sent';
