What are some potential pitfalls of using PHP to control button functionality based on user status?

One potential pitfall of using PHP to control button functionality based on user status is that it can lead to security vulnerabilities if not properly sanitized and validated. To solve this issue, always validate user input and sanitize data to prevent SQL injection and cross-site scripting attacks. 

// Example of validating and sanitizing user input before controlling button functionality

if(isset($_POST['button_click'])) {
    $user_status = filter_input(INPUT_POST, 'user_status', FILTER_SANITIZE_STRING);

    if($user_status == 'admin') {
        // Code to perform admin-specific functionality
    } else {
        // Code to perform default functionality
    }
}
