Laravel 5 - Namespace + Dynamic Model

Question

I have a very basic function to delete stuff on a simple website on Laravel 4.x that works like this:

public function delete()
{
    ...
    $Model = Input::get('Model');       
    $Action = $Model::find($Id);
   ...
}

Now on Laravel 5, I'm trying to do the same but so far I can't because the namespaces. Since the $Model is dynamic I don't want to make use for everything.

And something like this:

use App\C\Models as Model;

public function delete()
{
...
$Action = Model\$Model::find($Id);
...
}

Simple do not works. What'd be the right approach to get this to work?

Simply store the namespaced classname as a string first:

$Model = Input::get('Model');
$NamespacedModel = '\\Model\\' . $Model;
$Action = $NamespacedModel::find($Id);

@VinraGunantaPandia Maybe your PHP version is too old? I believe this was added in PHP 5.3

not because that, i must named variable with $class, $class = '\\Model\\' . $Model; $Action = $class::find($Id); and now its work

In the same case, My code is like this...

public function FunctionName(Request $request)
{
    $modelName = $request->model;

    $model = '\\App\\Models\\'.$modelName;

    $q = $model::find($request->id);

    $q->someColumn = 'someValue';

    $q->save();

    return back();
}

Note: I am using Laravel 8
