Should I create constructor with Setter? PHP

Question

Which best and safest method to create the constructor?

Netbeans creates direct by changing the variable, but has how to use Setter. So, which is the best and safest method? For example:

Without Setter

function __construct($nome, $idade, $sexo) {
        $this->nome = $nome;
        $this->idade = $idade;
        $this->sexo = $sexo;
    }

With Setter

function __construct($nome, $idade, $sexo) {
        $this->setNome($nome);
        $this->setIdade($idade);
        $this->setSexo($sexo);
    }
