How can sessions be used to store and retrieve the value of a variable like $seite in PHP?

To store and retrieve the value of a variable like $seite using sessions in PHP, you can set the variable value in a session variable when the page loads and retrieve it from the session when needed. This ensures that the variable value persists across different page loads for the same user.

// Start the session
session_start();

// Set the value of $seite in a session variable
$_SESSION['seite'] = $seite;

// Retrieve the value of $seite from the session
$seite = $_SESSION['seite'];
