Namespacs and creating a class object from a string with its name?

Question

Yii

Basically, I have a set of classes named ServiceXX, where XX is a changing string.
I use Yii2, I prescribe the namespace of the class through use.

namespace app\modules\tracking\classes;
use app\modules\tracking\classes\ServiceFI;
***
$serviceName = 'ServiceFI';
$service = new $serviceName;

I get the error "Class 'ServiceFI' not found".
Accordingly, if we use the notation:

$serviceName = 'app\modules\tracking\classes\ServiceFI';
$service = new $serviceName;

That object is created correctly.
Is it possible to somehow force the search by the provided namespace?

Answer 1

$serviceName = 'ServiceFI';
$model = 'app\\modules\\tracking\\classes\\' . $serviceName;
$service = new $model;
