Answer 1

错误消息告诉您确切的问题是什么

对等证书CN = server18.hostingraja.org' did not match expected CN=本地主机'

因此，您的代码（未显示）可能正在执行以下操作：

$mail->SMTPSecure = 'ssl';
$mail->Port = 465;
$mail->Host = 'localhost`;

这行不通，因为您无法获得localhost的可验证证书。解决此问题的两种方法：

$mail->SMTPSecure = false;
$mail->Port = 25;

这只是禁用了加密，您不需要加密，因为您只连接到本地主机。

$mail->SMTPSecure = 'ssl';
$mail->Port = 465;
$mail->Host = 'server18.hostingraja.org`;

这样，您仍然可以连接到同一台服务器，但是使用正确的名称，以便可以验证证书。

如果还有其他问题，请阅读错误消息链接到的故障排除指南，并在发布前进行搜索。
