使用 Prestashop 1.7 检索类别中的产品数量

Question

I am doing a first job on prestashop 1.7 I am currently trying to display a list of product categories

   $root_category_id = Context::getContext()->shop->getCategory();
        $category_tree = Category::getNestedCategories($root_category_id);
        $category_array = [];
        foreach ($category_tree[2]["children"] as $cat) {
 
            array_push($category_array, $cat);
        }

So far, it works. But, my problem is that I will also want to retrieve the number of products in each of the associated categories to display them with the name of the category

Check function getProducts() in classes/Category.php

public function getProducts(
        $idLang,
        $p,
        $n,
        $orderyBy = null,
        $orderWay = null,
        $getTotal = false, // To return count of products, pass this parameter as true
        $active = true,
        $random = false,
        $randomNumberProducts = 1,
        $checkAccess = true,
        Context $context = null
    )
