I used this one however

$to = "somebody@example.com";
$subject = "My subject";
$txt = "Hello world!";
$headers = "From: webmaster@example.com" . "\r\n" .
"CC: somebodyelse@example.com";

mail($to,$subject,$txt,$headers);

I have this error which is Failed to connect to mailserver at "localhost" port 25, verify your "SMTP" and "smtp_port" setting in php.ini or use ini_set()

Answer 1

如果你只是在localhost上运行你的应用程序而它尚未生效,我相信使用它发送邮件非常困难.

一旦您将应用程序联机,我相信这个问题应该自动解决.顺便说一句,ini_set()可以帮助您在运行时更改php.ini中的值.

这与在"localhost"端口25上连接到邮件服务器失败的问题相同

还检查这个PHP邮件功能不起作用
