【问题讨论】：

启用 SMTP 调试：$mail->SMTPDebug = 2;并检查它说什么
尝试使用端口587，因为465 是gmail 的端口，并且您已更新主机。
SMTP 错误：密码命令失败：535 5.7.8 @klian
@LovepreetSingh 更改端口没有帮助
错误 535 是身份验证问题。您必须检查凭据是否正确：SMTP 主机是否正确。用户名正确。密码正确。端口正确。认证方式正确。

【解决方案1】：

您可以更改第 459 行并将 split 函数替换为 explode 函数。

-  $toArr = split(',', $to);
+  $toArr = explode(',', $to);

【讨论】：

这与问题完全无关。 OP的问题是身份验证问题。
