I used this one however

$to = "[email protected]";
$subject = "My subject";
$txt = "Hello world!";
$headers = "From: [email protected]" . "\r\n" .
"CC: [email protected]";

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

If you are running your application just on localhost and it is not yet live, I believe it is very difficult to send mail using this.

Once you put your application online, I believe that this problem should be automatically solved. By the way,ini_set() helps you to change the values in php.ini during run time.
