php - 在while循环中使用PHPMailer发送多封电子邮件

Question

我试图在 while 循环中发送多封电子邮件，使用以下代码，它不发送电子邮件通知并给出错误“ fatal error : Uncaught Error :在 C:\xampp\htdocs\clinic\paients\run_medications 中找不到类“PHPMailer”。 php:98 堆栈跟踪:#0 {main} 被抛出。虽然位置正确并且从另一个子目录发送单个电子邮件。

您的 PHPMailerAutoload.php 文件在哪里？
你需要用这个导入它:

require_once('phpmailer/PHPMailerAutoload.php');

总体而言，您必须执行以下步骤:

从 https://github.com/PHPMailer/PHPMailer 下载包通过单击页面最右下方的“下载 ZIP”按钮。

解压缩文件。

将语言文件夹class.phpmailer.php、class.pop3.php、class.smtp.php和PHPMailerAutoload.php都上传到你服务器上的同一个目录中，我喜欢在服务器上创建一个名为phpmailer的目录来放置所有这些成。

在您的项目中加载类:
require_once('phpmailer/PHPMailerAutoload.php');

完毕...
