What additional status setting can be implemented at the beginning of a PHP script to prevent duplicate processing?

To prevent duplicate processing in a PHP script, you can implement a status setting using a flag variable. This flag variable can be set at the beginning of the script and checked throughout the script to ensure that the processing is only done once. By setting and checking this flag, you can prevent duplicate processing of the script. 

<?php

// Check if the script is already processing
if (!defined('PROCESSING_FLAG')) {
    define('PROCESSING_FLAG', true);

    // Your script code here
}

// Rest of the script
