Why is the variable (array) not accepted?

Question

Kohana

I'm trying to pass an array to a Kohana template..
This is how it works:

$errors = array('111',);

$content = View::factory('index/info/v_info_index')->bind('errors', $errors);

And if you do it like this:

$content = View::factory('index/info/v_info_index')->bind('errors', array('111'));

an error occurs:

ErrorException [ Fatal Error ]: Cannot pass parameter 2 by reference

Why is that? I'm betraying the same array

Answer 1

Because only variables can be passed by reference.
