php autoloader Fatal error: Class not found

Question

I am using PHP ActiveRecord with my small MVC framework thtat includes an autoloader. In my controller I access the model Pub::find(64) for example.

My problem is that Pub::find(64) is inheritating the namespace of the controller and I get the error

Fatal error: Class 'App\Controllers\Pub' not found in /home/i554246/public_html/mvc/App/Controllers/Index.php on line 27

Pub is the Module name. The file get included ok. I can solve this issue by appending \Pub::find(64) but this is not really intuitive for new people on the project.

Is there a way to stop the namespace appending for the Pub::find(64) without altering that line?

Index Controller

namespace App\Controllers;

class Index extends \Core\Controller
{
    protected
        $title = 'Home'
        ;

    /**
     * Default action
     */
    public function index()
    {
        // Pass the data to the view to display it
        $this->view->set('testdb', \Pub::find(64));

    }
}

App.php

/**
 * Class autoloader
 * @param $className
 * @see https://github.com/php-fig/fig-standards/blob/master/accepted/PSR-0.md
 */
public function autoload($className)
{
    preg_match('/(^.+\\\)?([^\\\]+)$/', ltrim($className, '\\'), $match);

    //Build namespace Autoloading
    $file = str_replace('\\', '/', $match[1]) . str_replace('_', '/', $match[2]) . '.php';

    //Build Model path
    $model = 'App/Models/' . $match[2] . '.php';

    if ( is_file($file) ) {
        require $file;
    }elseif ( is_file($model) ) {
        require $model;
    }

}

Models/Pub.php

class Pub extends ActiveRecord\Model
{
}

It seems you don't understand namespaces.

Since you are using namespace App\Controllers, the global namespace is denoted with \. So if you don't want to use fully-qualified name \Pub you have to put use declaration below the namespace, eg:

namespace App\Controllers;
use Pub;

PS: It's a good practice to put your models in a namespace too.
