What are the potential pitfalls of using outdated PHP functions like $HTTP_POST_FILES?

Using outdated PHP functions like $HTTP_POST_FILES can pose security risks as these functions are deprecated and may not be supported in future PHP versions. To avoid potential pitfalls, it is recommended to use the superglobal $_FILES array instead, which is the standard way to handle file uploads in PHP. 

// Using $_FILES superglobal instead of $HTTP_POST_FILES
if ($_SERVER['REQUEST_METHOD'] === 'POST') {
    $file = $_FILES['file'];
    // Handle file upload logic here
}
