Variable scope and functions in view - El Forum - 10-20-2012

Hey,
First of all, I know that the following thing it's unacceptable, but I don't have any choice, so don't tell me about it.
I tried to write this simple thing in the view (taken from PHP.net just for the example):
Code:
// view_test.php
<?php
$a = 1;
$b = 2;
function Sum()
{
global $a, $b;
$b = $a + $b;
}
Sum();
echo $b;
?>The controller is simple too:
Code:
class Draw extends MY_Controller {
function test()
{ $this->load->view('view_test'); }
}The result should be $b = 3, but $b = 2 and it doesn't refer to the `global` attitude, why does it happen and what can I do to get it works?
Thank you!

I'm talking about test it in view file (of CodeIgniter).

What are you actually trying to do? There has to be a far better solution than defining a function in the middle of your view (which is ugly).

You are absolutely right, the problem is that there is nothing to do. I'm trying to integrate a really ugly-code system which contains something like 20 files.
