user defined function in zend framework

Question

This piece of code is working fine with normal php:

<?php
function barber($type)
{
    echo "You wanted a $type haircut, no problem\n";
}
call_user_func('barber', "mushroom");
call_user_func('barber', "shave");
?>

How do i implement the same stuff with in an Action of a Zend controller ? (I believe Zend wont allow to call a function with in quotes and $this and self are not possible in this matter)

Answer 1

Create a method in your controller, eg

private function foo($var) {
    return $var++;
}

Call it like this using call_user_func()

call_user_func(array($this, 'foo'), $a);
