php备份整个项目并压缩然后发送邮件

直接上代码，php备份整个项目并压缩然后发送邮件，修改下面的邮箱配置和要备份的目录即可。

use PHPMailer\PHPMailer\Exception;
use PHPMailer\PHPMailer\PHPMailer;

// 需要使用phpmailer/phpmailer包，先进行包的引用
require 'vendor/autoload.php';

// 配置备份目录和邮件配置
$backupDir = '/www/wordpress5.6';  // 需要备份的目录
// 本地存储
$localPath = '/tmp/backup/';

$zipPassword = '';  // 可选的zip文件密码，为空表示不加密
$emailHost = 'smtp.163.com';  // 邮箱SMTP服务器地址
$emailUsername = 'xxx@163.com';  // 发件人邮箱
