What are the advantages and disadvantages of passing page information as a GET parameter in PHP?

Passing page information as a GET parameter in PHP can be advantageous as it allows for easy navigation and bookmarking of specific pages. However, it can also pose security risks as sensitive information is visible in the URL and can be easily manipulated. To mitigate this risk, sensitive information should not be passed via GET parameters and instead should be securely handled using sessions or other methods. 

// Example of passing page information as a GET parameter
<a href="page.php?page=about">About Us</a>

// Example of securely handling sensitive information using sessions
session_start();
$_SESSION['user_id'] = 123;
