Question

第一次发帖，所以任何帮助都非常感谢...

我很高兴SQL查询有效并返回两行
我很高兴留言，＃34;你好＆＃34;现在
我看了很多答案，没有解决我的问题
此功能仅将邮件发送给第一个（第2个）收件人，而不是第二个收件人。

如果有人能告诉我哪里出错了，我将非常感激......

Answer 1

首先，您应该首先检查PHPMailer文档，因为an example that does exactly this。你不可能看起来太难。

在你的代码中，不要每次在循环周围创建一个新的PHPMailer实例 - 所有保持不变的东西（isSmtp，Host，Port等）应该在循环之前设置一次。在循环中你应该做这些事情：

设置邮件正文
设置收件人
发送消息
存储任何错误
清除收件人列表（使用clearAllRecipients()）

您的发送检查后您还收到了return个语句 - 这些语句将完全退出您的功能，因此它永远不会发送多条消息。您应该在列表中收集错误并在最后显示（或返回）它们。

Answer 2

我在上面的@synchro建议的addAddress周围使用了一个while循环。 Foreach迭代器语法不会像我使用PHP 5.3一样工作（根据上面PHPmailer链接中的注释）。

然后我在while循环之外接受了返回，一切正常。

这是有效的代码：（感激地接受任何改进）
