How can a unique value be included in each page to verify user identity in PHP session management?

To include a unique value in each page to verify user identity in PHP session management, you can generate a random token when the user logs in and store it in the session. This token can then be included in each page as a hidden input field or as part of the URL parameters to verify the user's identity. 

<?php
session_start();

// Generate a random token
$token = bin2hex(random_bytes(16));

// Store the token in the session
$_SESSION['token'] = $token;
?>

<!DOCTYPE html>
<html>
<head>
    <title>Page Title</title>
</head>
<body>
    <form action="verify.php" method="post">
        <input type="hidden" name="token" value="<?php echo $_SESSION['token']; ?>">
        <!-- Other form fields -->
        <button type="submit">Submit</button>
    </form>
</body>
</html>
