Hello @muraduk

I think you are using PHP 7.2 and Magento support only for 2.3 with php 7.2 so please change php version according to Magento version 

or 

Change

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

To

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

Hi @muraduk,

You can use the PHP below version like 2.1.11 or otherwise you can upgrade your site to the new version.

If my solution is useful, give kudos & accept as solution

Hello @muraduk

I think Database which you imported is corrupted or you can remove the entry from the setup_module table for "adminhafot_mag2.flag" and run again setup:upgrade command.
