PHP注册/电子邮件验证

Question

Thanks in advance. Below is code from PHPmailer (https://github.com/Synchro/PHPMailer) which is giving me a few problems. It works along side this PHP sign-up (http://www.codingcage.com/2015/09/login-registration-email-verification-forgot-password-php.html). I know it works other then the email because the table in the database does recieve the values. I can manually update the table and and allow myself to log-in. It does send out a Error 500 page.

function send_mail($email,$message,$subject)
{      
    require_once('class.phpmailer.php');
    $mail = new PHPMailer();
    $mail->IsSMTP(); 
    $mail->SMTPDebug  = 1;                     
    $mail->SMTPAuth   = true;                  
    $mail->SMTPSecure = "ssl";                 
    $mail->Host       = "smtp.gmail.com";      
    $mail->Port       = 465;             
    $mail->AddAddress($email);
    $mail->Username = "[e-mail]";  
    $mail->Password = "PASSWORD";            
    $mail->SetFrom('[e-mail]','Coding Cage');
    $mail->AddReplyTo("[e-mail]","Coding Cage");
    $mail->Subject = $subject;
    $mail->MsgHTML($message);
    $mail->Send();
}
