How can the PHP script be improved to handle cases where $_POST is empty upon direct script invocation?

When $_POST is empty upon direct script invocation, it can lead to errors or unexpected behavior in the script. To handle this situation, you can check if $_POST is empty and initialize it as an empty array if it is. This ensures that the script can safely access $_POST variables without causing errors. 

<?php
// Check if $_POST is empty and initialize as an empty array if it is
if (empty($_POST)) {
    $_POST = [];
}

// Now you can safely access $_POST variables without errors
// For example, accessing a specific POST variable
$variable = isset($_POST['variable']) ? $_POST['variable'] : null;

// Rest of your PHP script goes here
?>
