Stupid question about include()

[eluser]Phoenixheart[/eluser]
(Sorry, but I am new to CI)
Assuming I have a controller at projects.php, in which I have GetProjects() function. Also I have a view called projects_view.php.
I wanted to call GetProjects() along with the view. So in projects_view.php I put this code:

Code:

// my HTML here
<?php
    include('index.php/projects/GetProjects');
?>
// my HTML here

But I received this error:

Code:

Message: include(index.php/projects/GetProjects) [function.include]: failed to open stream: No such file or directory

Does it mean we can't use php's include() with CI's URI? Or am I doing something wrong?
Thanks in advance!
