How can headers be effectively used in PHP to redirect users after editing and updating data in a form?

To redirect users after editing and updating data in a form in PHP, you can use the header() function to send a raw HTTP header to the browser, which will redirect the user to a new page. Make sure to call the header() function before any output is sent to the browser to avoid any errors.

// Process form data and update database

// Redirect user to a new page after updating data
header("Location: new_page.php");
exit();
