I have a function in my controller that receives some requests, and in the end everything is stored in two arrays. In this function, if I do the following:

 return view('negocio.detalhes-trajetoa', compact('arrayLogradourosA', 'arrayLogradourosB'));

I can access these two arrays in this view.

But my goal is to pass these two arrays to another function of my controller, to look like this:

public function outraFuncao () {
    return view('negocio.detalhes-trajetoa', compact('arrayLogradourosA', 'arrayLogradourosB'));
}

But as these two arrays are in another function of my controller, in my view it gives that error "Undefined variable".

How can I share these two arrays for another function in my controller ??

The function compact only works with local scope variables.

To reuse these variables you need to pass them to the new method.

public function routeEndpoint() {
    // ..

    return $this->outraFuncao($arrayLogradourosA, $arrayLogradourosB);
}

private function outraFuncao ($arrayLogradourosA, $arrayLogradourosB) {
    return view(
        'negocio.detalhes-trajetoa', 
        compact('arrayLogradourosA', 'arrayLogradourosB')
    );
}

So I understand this second method is used internally by the other endpoints of controller routes. So its visibility does not have to be public and in the example I changed it to private .

Look, you can define global variables in your controller:

class TestController extends Controller
{
    private $arrayLogradourosA;
    private $arrayLogradourosB;

    public function funcao1($cidade, $cidade2)
    {
        $this->$arrayLogradourosA = Logradouros::where('cidade', $cidade)->get();
        $this->$arrayLogradourosB = Logradouros::where('cidade', $cidade2)->get();
    }

    private function outraFuncao() { 
        $arrayLogradourosA = $this->arrayLogradourosA;
        $arrayLogradourosB = $this->arrayLogradourosB;

        return view(
            'negocio.detalhes-trajetoa', 
            compact('arrayLogradourosA', 'arrayLogradourosB')
        );
    }
}

It's a generic example, because I did not really understand why it was not all in one function.
