i have the problem in the code , but i do not see it

In the video we write the code. I have the problem because my code show this : "Product name: default_nameFlavor:" but in the course need : "Product name: Space Juice Soda Flavor: Grape "; maby because i am heedless ;-)

class Product 
{

    public $name = 'default_name';
    public $price = 0;
    public $desc = 'default decripion';

    function _construct($name, $price, $desc){
        $this->name = $name;
        $this->price = $price;
        $this->desc = $desc;

    }

    //method
    public function getInfo(){
        return "Product Name: ". $this->name;

    }

}

class Soda extends Product
{

    public $flavor;

    function _construct($name, $price, $desc, $flavor){
        parent::__constract($name,$price,$desc);
        $this->flavor = $flavor; 
    }

    public function getInfo(){
        return "Product name: ". $this->name . "Flavor: " . $this->flavor;
    }
}

$shirt = new Product("Space Juice T-Shirt", 20, "Awesome T-Shirt");
$soda = new Soda("Space Juice Soda", 2, "Thirst Mutilator", "Grape");

echo $soda->getInfo();

I can see this: the method construct is called in the wrong way: first, the function should be called __construct($property1,$property2,$property3,$new_property); then, when you call the parent class with the parent key parent:: you should write it the same way as above

I see an underscore missing from the construct except the call to the parent. Should be 2 underscores like __construct. And parent construct is misspelled. 

class Product {

public $name = 'default_name';
public $price = 0;
public $desc = 'default decripion';

function __construct($name, $price, $desc){
    $this->name = $name;
    $this->price = $price;
    $this->desc = $desc;

}

//method
public function getInfo(){
    return "Product Name: ". $this->name;

}

}

class Soda extends Product {

public $flavor;

function __construct($name, $price, $desc, $flavor){
    parent::__construct($name,$price,$desc);
    $this->flavor = $flavor; 
}

public function getInfo(){
    return "Product name: ". $this->name . "Flavor: " . $this->flavor;
}

}

$shirt = new Product("Space Juice T-Shirt", 20, "Awesome T-Shirt"); 
$soda = new Soda("Space Juice Soda", 2, "Thirst Mutilator", "Grape");

echo $soda->getInfo();
