Hi Uma,

The notices which you are getting is because you are trying to access an undefined variable.

In your code:

$user = $_POST['username'];

You are storing a post value in to $user variable directly.

If you are storing a post value in to a variable, check for the condition as below.

if(isset($_POST['username']) && !empty($_POST['username'])) {
$user = $_POST['username'];
}

PHP self returns the URL for the page in the browser.

Please do go through the below link:
