How can PHP sessions be utilized to store and retrieve user-selected category values for search functionality?

To store and retrieve user-selected category values for search functionality using PHP sessions, you can set the selected category value in a session variable when the user selects a category. Then, when the user performs a search, you can retrieve the selected category value from the session and use it to filter the search results accordingly. 

// Start the session
session_start();

// Set the selected category value in a session variable
if(isset($_POST['category'])) {
    $_SESSION['selected_category'] = $_POST['category'];
}

// Retrieve the selected category value from the session
if(isset($_SESSION['selected_category'])) {
    $selected_category = $_SESSION['selected_category'];
    // Use the selected category value to filter search results
    // Example: $search_results = perform_search($selected_category);
}
