What is the role of header() function in PHP and how can it be used to redirect users to a specific page without them noticing?
The header() function in PHP is used to send raw HTTP headers to the browser. By using the header() function with the "Location" parameter, you can redirect users to a specific page without them noticing. This can be useful for scenarios where you want to redirect users after performing a certain action without displaying the redirection process.
<?php
// Redirect users to a specific page without them noticing
header("Location: https://www.example.com/newpage.php");
exit;
?>
