在函数内创建对象

Question

I am trying to create object of class within function. But PHP keeps telling me, that class is not found. Class is defined in another file included via autoload. My code is:

require_once('inc/eet/autoload.php');
require_once('inc/eet/eet_functions.php');

use Ondrejnov\EET\Exceptions\ServerException;
use Ondrejnov\EET\Dispatcher;
use Ondrejnov\EET\Receipt;
use Ondrejnov\EET\Utils\UUID;

var_dump(sendEET(1111597719, 'eshop'));

Part of file eet_function.php is:

function sendEET ($number, $type){
$dispatcher = new Dispatcher(PRODUCTION_WSDL, 'xxx.key', 'xxx.pem');  
....
}

And the error is:

Fatal error: Class 'Dispatcher' not found in /var/www/clients/client1/web3/web/inc/eet/eet_functions.php on line 14 E_ERROR Error in file »eet_functions.php« at line 14: Class 'Dispatcher' not found

Can you please help me sort it out? Thank you very much!
