发现PHPMailer又做了较大的更新，以前发送邮件的方法已不太适用，刚好要做一个实验，需要搭建个环境，这里使用Gmail进行测试，现记录下来。
传送地址Github: PHPMailer
基本要求的内容跟之前的文章是一样的： phpmailer 发送邮件(一)
一、基本要求
- Web访问正常（apache可以正常访问）
- php 设置正确(Sockets Support、OpenSSL support 两项设置为enable)
- gmail设置， 允许不够安全的应用：设置为已启用
可以写一个简单的语句测试一下：info.php
<?phpphpinfo();?>
二、PHPmailer
新版的PHPMailer跟之前的最大不同在于需要使用composer， ubuntu 下composer的安装可参考：ubuntu 安装 php Composer
安装完成之后，我们需要使用composer来下载PHPMailer。
我们先切换到web跟目录，创建一个phpmailer的目录，切换到该目录，然后使用命令下载文件：composer require phpmailer/phpmailer， 这个过程会耗费点时间。
lz@starnight:/var/www/html$ pwd/var/www/htmllz@starnight:/var/www/html$ lshello.html ?index.html ?info.php ?phpmailerlz@starnight:/var/www/html$ cd phpmailer/lz@starnight:/var/www/html/phpmailer$ composer require phpmailer/phpmailer
下载完成之后，我们可以看到目录下多了一些文件，我们创建一个新的文件mailer.php用来发送文件。
lz@starnight:/var/www/html/phpmailer$ pwd/var/www/html/phpmailerlz@starnight:/var/www/html/phpmailer$ lscomposer.json ?composer.lock ?mailer.php ?vendorlz@starnight:/var/www/html/phpmailer$ ls vendor/autoload.php ?composer ?phpmailer
mailer.php的内容如下：
<?php// Import PHPMailer classes into the global namespace// These must be at the top of your script, not inside a functionuse PHPMailer\PHPMailer\PHPMailer;use PHPMailer\PHPMailer\Exception;//Load composer‘s autoloaderrequire ‘vendor/autoload.php‘;$mail = new PHPMailer(true); ?????????????????????????????// Passing `true` enables exceptionstry { ???//Server settings ???$mail->SMTPDebug = 2; ????????????????????????????????// Enable verbose debug output ???$mail->isSMTP(); ?????????????????????????????????????// Set mailer to use SMTP ???$mail->Host = ‘smtp.gmail.com‘; ?// Specify main and backup SMTP servers ???$mail->SMTPAuth = true; ??????????????????????????????// Enable SMTP authentication ???$mail->Username = ‘starnightcyber@gmail.com‘; ????????????????// SMTP username ???$mail->Password = ‘your password‘; ??????????????????????????// SMTP password ???$mail->SMTPSecure = ‘tls‘; ???????????????????????????// Enable TLS encryption, `ssl` also accepted ???$mail->Port = 587; ???????????????????????????????????// TCP port to connect to ???//Recipients ???$mail->setFrom(‘starnightcyber@gmail.com‘, ‘starnightcyber‘); ???$mail->addAddress(‘starnight_cyber@foxmail.com‘); ??????????????// Name is optional ???$mail->addAddress(‘zl15@foxmail.com‘); ???//Attachments // ??$mail->addAttachment(‘/var/tmp/file.tar.gz‘); ????????// Add attachments // ??$mail->addAttachment(‘/tmp/image.jpg‘, ‘new.jpg‘); ???// Optional name ???//Content ???$mail->isHTML(true); ?????????????????????????????????// Set email format to HTML ???$mail->Subject = ‘Test mail.‘; ???$mail->Body ???= ‘Hello, this is a test mail using phpmailer‘; ???$mail->AltBody = ‘Hello, this is a test mail using phpmailer‘; ???$mail->send(); ???echo ‘Message has been sent‘;} catch (Exception $e) { ???echo ‘Message could not be sent.‘; ???echo ‘Mailer Error: ‘ . $mail->ErrorInfo;}?> 访问站点：
等待一会（可能会比较慢，取决于你的网络状况），我们可以看到邮件被成功的发送出去了，下面是发送邮件的日志信息和相关截图。

另外，上面代码中给出的邮箱都是有效的邮箱地址，没有打码，只是为了让各位能更清楚的看到效果，请改成自己的邮箱，不然自己也看不到是否发送成功，别瞎几把给我发邮件^_^。
