I don't understand why they didn't place this declaration to class not into the method. I would do it so and accessed like so:
$this->_is_loaded[strtolower($class)] = $class;

Because it's a globally scoped function, not a class property.

Oh. I didn't see. Common.php isn't class.

I understand. Every item ($_classes) in the array is string, right?

No every item is an object

I see now L166:

Code:

$_classes[$class] = new $name();

OK. So new object with class name $name is added to the array $_classes.
And then it is returned L167. But this object is not accessible from super object. Hence it is returned by function load_class (common.php).

Code:

return $_classes[$class];

That is the &load;_class. Clear.

I guess I should to see the difference between $_classes in global scoped function and $ci_classes in super object. In loader.php is used $ci_classes, in common.php is used $_classes...
