Convert a $_GET value in PDO - sql

Question

I wrote a basic function to join 3 tables regarding a similar id.
{
$id = $_GET["id"];
$product_edit_query = $this->DB->query('
SELECT * FROM products
LEFT JOIN products_ingredients
ON products_ingredients.product_id = products.product_id
LEFT JOIN products_languages
ON products_languages.product_id = products.product_id
WHERE products.product_id = 73
');
$product_edit = $product_edit_query->fetch();
$this->smarty->assign('product_edit', $product_edit);
}
In the last line I have of my request, i have WHERE products.product_id = 73. 73 is hardcoded, and should be the value of $_GET["id"], but all I tried didn't work to convert it in PDO, any help ?

Solution given by a friend:
{
$stmt = $this->DB->prepare('
SELECT * FROM products
LEFT JOIN products_ingredients
ON products_ingredients.product_id = products.product_id
LEFT JOIN products_languages
ON products_languages.product_id = products.product_id
WHERE products.product_id = :id
');
$stmt->execute([':id' => $_GET["id"]]);
$get_product_base = $stmt->fetch();
$this->smarty->assign('get_product_base', $get_product_base);
}
