Are there any potential pitfalls to using JavaScript for automatically deleting user entries when a page is closed in PHP?

When using JavaScript to automatically delete user entries when a page is closed in PHP, one potential pitfall is that the user may have JavaScript disabled, which would prevent the deletion from occurring. To solve this issue, you can also implement the deletion logic in PHP by using session variables to track the user's entries and deleting them when the session is closed. 

session_start();

// Check if user entries exist in session
if(isset($_SESSION['user_entries'])){
    // Delete user entries
    unset($_SESSION['user_entries']);
}
