What are the advantages and disadvantages of using the user ID as the folder name instead of the email address in PHP?

Using the user ID as the folder name instead of the email address can provide better security and privacy since user IDs are typically unique and not easily guessable. However, it may be less user-friendly and require additional steps to map the user ID to the corresponding email address when needed. 

$userID = 12345;
$folderName = "user_" . $userID;
// Use $folderName in your code instead of the email address
