     $mail = new PHPMailer(true);

           //Send mail using gmail
           if($send_using_gmail){
           $mail->IsSMTP(); // telling the class to use SMTP
    $mail->SMTPAuth = true; // enable SMTP authentication
    $mail->SMTPSecure = "ssl"; // sets the prefix to the servier
    $mail->Host = "smtp.gmail.com"; // sets GMAIL as the SMTP server
    $mail->Port = 465; // set the SMTP port for the GMAIL server
    $mail->Username = "example"; // GMAIL username
    $mail->Password = "password"; // GMAIL password
}

//Typical mail data
$mail->AddAddress($email, $name);
