How to use a variable that returns a return

I'm pretty clumsy with the functions, and more with the use of return .

I have this code:

    public function addAuthor($autor, $nacimiento, $descripcion) {
        $sql = $this->db->prepare("INSERT INTO autores (Autor, Nacimiento, Descripcion) VALUES (:autor, :nacimiento, :descripcion)");
        $sql->execute(array(':autor'=>$autor, ':nacimiento'=>$nacimiento, ':descripcion'=>$descripcion));

        $lastID = $this->db->lastInsertId('IDAutor');

        return $lastID;
    }

I need to use the $lastID to be able to rename the photo with the id and then upload it.

this is the driver code:

$c->addAuthor($name, $nacimiento, $description);

How would I get the result of $lastID ? Should we call the function in another way? I am very lost with the issue of return . I tried to read in the PHP guide on the return but I still do not see the form.

So that the question is not open, if its function is correctly written and it returns the expected values, it would only have to assign the value to a variable X to use that value where it is required.

/* En la variable $id tendrá el valor devuelto por la función */
$id = $c->addAuthor($name, $nacimiento, $description);
