Hello, everyone.
I am using badwords-filter npm and it is using create_function(). 
But as you know that function is removed from php 8.
So it is getting error now and I can't sure how to fix it.
If you are familiar with it, please help me.
    private function flattenArray($array)
    {
        $objTmp = (object)['aFlat' => []];
        array_walk_recursive($array, create_function('&$v, $k, &$t', '$t->aFlat[] = $v;'), $objTmp);
        return $objTmp->aFlat;
    }
On the above code, the create_function() is getting error.
