Code:

/*

|  Native Autoload - by Phil Sturgeon.

|
| Nothing to do with config/autoload.php, this allows PHP autoload to work
| for base controllers and some third-party libraries.
|
| If using HMVC you do not need this! HMVC will autoload.
|
| Place this code at the bottom of your application/config/config.php file.

function __autoload($class)

    if (strpos($class, 'CI_') !== 0)
    {
        @include_once(APPPATH . 'core/' . $class . EXT);
