session_start(); if (!isset($_SESSION['user_id'])) { header('Location: login.php'); exit(); }
session_start(); if ($success) { $_SESSION['user_id'] = $user_id; header('Location: home.php'); exit(); }In this example, the session_start() function is called to start the session. After a successful login, the user_id session variable is set to the user's ID. The header() function is used to send a redirect response to the home.php page. This example also uses the header() function which is part of the PHP standard library. In conclusion, the PHP Session redirect technique relies on PHP session variables to store and pass information between pages. The header() function is commonly used to send a redirect response. These functions are part of the PHP standard library.
