php - How do I send an email from gmail within my app? -

i have following code. send confirmation email user click 'register' button. when click on register button database gets updated correct information doesn't send email.

email.php:

<?php include('class.phpmailer.php'); include('class.smtp.php'); $mail  = new phpmailer();    $mail->issmtp();  //gmail config $mail->smtpauth   = true;                  // enable smtp authentication $mail->smtpsecure = 'ssl';                 // sets prefix server $mail->host       = 'smtp.gmail.com';      // sets gmail smtp server $mail->port       = 465;                   // set smtp port gmail server $mail->username   = 'xxx@gmail.com';  // gmail username $mail->password   = 'yyy';            // gmail password //end gmail  $mail->from       = 'xxx@gmail.com'; $mail->fromname   = 'sys'; $mail->subject    = 'registration successful'; $mail->msghtml('you have been added system!');  $mail->addaddress($_post['emailaddress']); $mail->ishtml(true); // send html  if(!$mail->send()) {//to see if return message or value bolean     echo "mailer error: " . $mail->errorinfo; } else  echo "message sent!";  ?>
