Warning Count Magento 2.2 & PHP 7.2

Question

I receive the warning after upgrading to PHP 7.2 while running magento still in 2.2. Warning: count(): Parameter must be an array or an object that implements Countable in /vendor/magento/module-catalog/Model/Product/Option/Type/Select.php on line 71

i tried changing count, but i am stuck.

   if (!$this->_isSingleSelection()) {
            $valuesCollection = $option->getOptionValuesByOptionId($value, $this->getProduct()->getStoreId())->load();
            if ($valuesCollection->count() != count($value)) {
                $this->setIsValid(false);
                throw new LocalizedException(__('Please specify product\'s required option(s).'));
            }
        }
        return $this;
    }

Answer 1

Magento 2.2 not working with php 7.2, you need to upgrade to Magento 2.3.4

or you can install 2 php versions and change php for magento.

for example for CentOS /RHEL configuration: https://rpms.remirepo.net/wizard/

Answer 2

Thank you for your answer. At the moment i only experience this problem, all others have been fixed.

This behaviour only occurs if i try to add a product with radiobutton additions instead of check boxes. As corona is hitting my business very hard and my hoster will disable php 7.1 at 1st of april i need to find a way around. updating my shop is to expensiv at the moment as i have a very custom checkout but still need to pay my employees..

I found out i only need to change the way how count() is used but this function is to difficult for me.
