Php versions – php constructor in a field assign the last value

Php version is 7.1.
I want to initialize class fields with values, but it fails.

Why does php in a class constructor in a field assign the last value?

class Order
{
    private $yourname;
    private $yourphone;

    public function __construct(string $p_yourname, string $p_yourphone) 
     { 
        $this->$yourphone =$p_yourphone;
        $this->$yourname=$p_yourname;

    echo  $p_yourname;
    echo  $p_yourphone;
    echo  $this->$yourphone;
    echo  $this->$yourname;
     }
}

call conctructor

$order = new Order( 'Andry', '+79777475675');

Result in echo is: Andry+79777475675AndryAndry

    Clear. The parameter name and the field name in the constructor must be the same. The syntax for assignment in the constructor should be like this $this->yourphone =$yourphone;

    That's right so

    public function __construct(string $yourphone, string $yourname) 
     { 
        $this->yourphone =$yourphone;
        $this->yourname=$yourname;
        echo  $yourphone;
        echo  $yourname;
        echo  $this->$yourphone;
        echo  $this->$yourname;
     }

    Correction:

    class Order
{
    private $yourname;
    private $yourphone;

    public function __construct(string $p_yourname, string $p_yourphone) 
     { 
        $this->yourphone =$p_yourphone;
        $this->yourname=$p_yourname;

    echo  $p_yourname;
    echo  $p_yourphone;
    echo  $this->yourphone;
    echo  $this->yourname;
     }
}
