Loading core controller as well as composer libraries

There are other ways to make this work. HERE is a page that discusses all the variations.

I am not a fan of putting more than one class in a file but it does work. I prefer using the "hooks" method as described on the linked page.

You can put your autoload into config.php and fix the conflict problem with simple changes.

PHP Code:

function my_autoloader($class)
{
   if (strpos($class, 'CI_') !== 0)
   {
       if (file_exists($file = APPPATH . 'core/' . $class . '.php'))
       {
           include $file;
       }
       elseif (file_exists($file = APPPATH . 'libraries/' . $class . '.php'))
       {
           include $file;
       }
   }
}

spl_autoload_register('my_autoloader'); 


By using spl_autoload_register() you allow multiple autoload functions to live in harmony - including the composer autoloader.
