How can sessions be effectively utilized in PHP to track and manage the display of different text sections from a file?

To track and manage the display of different text sections from a file using sessions in PHP, you can store the current section being displayed in a session variable. This way, you can easily switch between different sections without losing track of the user's progress. 

<?php
session_start();

// Check if a section is already set in the session
if(isset($_SESSION['current_section'])) {
    $current_section = $_SESSION['current_section'];
} else {
    // Set a default section if none is set
    $current_section = 'section1';
}

// Display the text content based on the current section
switch($current_section) {
    case 'section1':
        echo "Text for section 1";
        break;
    case 'section2':
        echo "Text for section 2";
        break;
    // Add more cases for additional sections
}

// Update the current section based on user input
if(isset($_GET['section'])) {
    $_SESSION['current_section'] = $_GET['section'];
}
?>
