In Perch (non-runway) 3.1.2 on PHP 7.2.4 I'm getting the following warning when calling the shop function perch_shop_cart(); :

Warning: count(): Parameter must be an array or an object that implements Countable in /Users/mwesten/Sites/pls.test/beheer/addons/apps/perch_shop/lib/PerchShop_Cart.class.php on line 516

Changing line 516 in PerchShop_Cart.class.php from:

        if (count($json)) {

to

        if (PerchUtil::count($json)) {

Seems to fix it...?
