You PHP installation (XAMPP, by the looks of it) does not support SSL. Ensure that the line
extension=php_openssl.dll
is not commented out in your php.ini, restart Apache, and if that still doesn't work try overwriting (or copying) ssleay32.dll and libeay32.dll from your PHP directory into Apache's binary (.exe) directory then restart Apache.
First of all when you get error messages then that's great! Because in 90% of the cases you find that others have had them too and therefore you'll find plenty of information on the internet about this error message.
So step 1 when getting an error message you don't know yet is always open google and copy paste it there. But, take out any paths or other things which are uniquely connected to your system.
Then about your errors. Especially xampp light doesn't support SSL. Maybe you try an easier sendmail example first. Like a very small one and then increase it step by step. That's what I always do, when I don't know why something doesn't work. I start with one line and see what it does, then I add another and so forth.
Let's say you start with this and see if it works:
<?php
include("class.phpmailer.php");
$mail = new PHPMailer();
$mail->IsSMTP();
$mail->SMTPAuth = true; // enable SMTP authentication
$mail->Host = "smtp.gmail.com"; // sets GMAIL as the SMTP server
$mail->Port = 465; // set the SMTP port for the GMAIL server
$mail->Username = "[email protected]"; // GMAIL username
$mail->Password = "xxxxxxxx"; // GMAIL password
$mail->From = "[email protected]";
$mail->Subject = "PHPMailer Test Subject via gmail";
$mail->Body = "Hi, this is a test";
$mail->AddAddress("[email protected]", "Hussain");
$mail->send();
?>
oh, and btw. your mail from has a .com too many!
