How can changes to navigation links in PHP code affect user permissions and access levels?

When making changes to navigation links in PHP code, it is important to ensure that the links are properly restricted based on user permissions and access levels. This can be achieved by implementing conditional statements in the code that check the user's permission level before displaying certain navigation links. By doing so, unauthorized users will not have access to links that they are not permitted to view. 

<?php
// Check user's permission level
$userPermissionLevel = 2; // Example permission level

// Display navigation links based on user's permission level
if($userPermissionLevel >= 2){
    echo '<a href="dashboard.php">Dashboard</a>';
}

if($userPermissionLevel >= 1){
    echo '<a href="profile.php">Profile</a>';
}

if($userPermissionLevel >= 3){
    echo '<a href="admin.php">Admin Panel</a>';
}
?>
