Run another function in controller class - Background process

[eluser]cinewbie81[/eluser]
Hi all,

In my "Main" Controller index function, i want to call the index() function from "SendSMS" controller class. How can i do it ?
I know it can be done using redirect("SendSMS") statement, but I don't want it to be this way. Instead, i want the SendSms index() function to be running as background process(using the '&' symbol). How can i do it ? Anyone ??

Thanks.

Code:

<?php

class Main extends Controller {
    
    function index()
    {
        // I want to run mybackground_function() here from Runbackground controller
    }
}
?>

Code:

<?php
class SendSMS extends Controller {
    
    function index()
    {
        // sending thousands of SMS here
    }
}
?>
