redis error with cache:clean

[Sheba]

Greetings,

How do I clear cache without Redis? 

Which directories are cleared with cache:clean?

I restored a 2.2.6 backup got this message

Deprecated: The each() function is deprecated. This message will be suppressed on further calls in /home/site/public_html/vendor/magento/zendframework1/library/Zend/Cache/Backend.php on line 79
An error has happened during application run. See exception log for details. Could not write error message to log. Please use developer mode to see the message.

>>> when I try to clear cache with php bin/magento cache:clean or flush, Redis Error <<<

Thanks for your attention.

Hi @Sheba 

each() function is deprecated in php 7.2 so change this function to foreach()

Change

 while (list($name, $value) = each($options)) {
        $this->setOption($name, $value);
    }

To 

foreach ($options as $name => $value){
        $this->setOption($name, $value);
    }
