How can session variables be utilized to track and manage randomly selected questions in PHP?

Session variables can be utilized to track and manage randomly selected questions in PHP by storing the selected questions in the session array. This allows the selected questions to persist across multiple pages or requests during a user's session. 

// Start the session
session_start();

// Check if selected questions array exists in session
if (!isset($_SESSION['selected_questions'])) {
    $_SESSION['selected_questions'] = array();
}

// Generate a random question and add it to the selected questions array
$randomQuestion = "Random question...";
$_SESSION['selected_questions'][] = $randomQuestion;

// Display the selected questions
foreach ($_SESSION['selected_questions'] as $question) {
    echo $question . "<br>";
}
