SPL_AUTOLOAD_REGISTER overriding PHP Extensions

Question

I've written a quick autoloading script for php, although it seems as though the autoloading is overriding php extensions and such.

I'm creating a database class for pdo, and I need to implement PDO within the class. The issue with this is that PHP thinks that PDO is a class located in the same namespace as my database class.

index.php;

use database\db;
require_once "core/inc.php";
$db = DB::instance();

core/inc.php;

spl_autoload_register(function($a) {
    $file;
    if(file_exists($file = dirname(__DIR__) . DIRECTORY_SEPARATOR . "module" . DIRECTORY_SEPARATOR . str_replace("\\", DIRECTORY_SEPARATOR, strtolower($a)) . ".php"))
        require_once $file;
});

module/database/db.php;

namespace database;
$this->_pdo = new PDO('mysql:host=' . $config->get('database/ip') . ';dbname=' . $config->get('database/db'), $config->get('database/un'), $config->get('database/pw'));

I haven't really touched namespaces before in PHP, so I cannot find a viable solution around this. I've been researching quite a bit and trying to find a fix, although I have yet to succeed in that task.

Any help would be appreciated,
Cheers.

Tell your code that PDO is in the global (\) namespace, not in the specified namespace

namespace database;
$this->_pdo = new \PDO('mysql:host=' . $config->get('database/ip') . ';dbname=' . $config->get('database/db'), $config->get('database/un'), $config->get('database/pw'));
