Are there best practices for setting and using $_Session variables in PHP for navigation?

When setting and using $_SESSION variables in PHP for navigation, it is important to follow best practices to ensure security and efficiency. One common approach is to set a $_SESSION variable to store the current page or section the user is on, and then use this variable to determine which content to display or which actions to perform. It is also important to validate and sanitize the $_SESSION variable to prevent any security vulnerabilities. 

// Set the $_SESSION variable for navigation
$_SESSION['current_page'] = 'home';

// Use the $_SESSION variable to determine which content to display
if ($_SESSION['current_page'] == 'home') {
    // Display home page content
} elseif ($_SESSION['current_page'] == 'about') {
    // Display about page content
} else {
    // Handle other cases
}
