Answer 1

错误消息告诉您问题所在

Peer certificate CN=server18.hostingraja.org' did not match expected CN=localhost'

所以您的代码（您没有显示）可能在做类似的事情：

$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;

这只是禁用加密，您不需要加密，因为您只是连接到本地主机。

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

这样您仍然连接到同一台服务器，但使用正确的名称以便可以验证证书。

如果您有任何其他问题，请阅读错误消息链接到的故障排除指南，并在您之前进行搜索post。
