How can PHP be used to set bandwidth limits and create folders accessible only to admins and users?

To set bandwidth limits in PHP, you can track the amount of data transferred by each user and restrict access once a certain limit is reached. To create folders accessible only to admins and users, you can use PHP to check the user's role or permissions before allowing access to the folder.

// Check bandwidth limit for user
$bandwidthLimit = 1000000; // 1MB
$bandwidthUsed = // calculate the amount of data transferred by the user
if($bandwidthUsed > $bandwidthLimit){
    // restrict access
    die("Bandwidth limit exceeded");
}

// Check user role for folder access
$userRole = "admin"; // or "user"
$folderPath = "/path/to/folder/";
if($userRole != "admin"){
    // restrict access for non-admin users
    die("Access denied");
}

// Continue with folder access for admins
// code to access folder
