       {
   
           // might need to call <code>set_time_limit</code> here
           set_time_limit(0);

               include 'orders.php';

 * Cron’s purpose is re-running commands at certain intervals. If you want to run
   code only once and only in a specific scenario within wordpress, that’s a sign
   you should actually be looking for a hook.
 * To run a function only once after activation of a specific plugin of yours, you
   probably want to use the ‘register_activation’ hook within that plugin:
    [https://developer.wordpress.org/reference/functions/register_activation_hook/](https://developer.wordpress.org/reference/functions/register_activation_hook/)
 * If it’s not your plugin and you can’t/shouldn’t just add code to it, this either
   doesn’t apply or there’s another hook for that.
