It seems like you are calling the size function count() as part of the test condition. You might want to compute the size beforehand, and not on each iteration.

                    $values[$arr[$i - 1]] = $arr[$i];
                }

                return $values;
            }
        }

        return json_decode($value);

It seems like $value can also be of type object; however, parameter $json of json_decode() does only seem to accept string, maybe add an additional type check?

The condition is_array($value) is always true.

            $values = '';
            foreach ($value as $k => $v) {
                $values .= ($values ? ',' : '')."'$k','$v'";
            }

            return DB::raw("column_create($values)");
        }
//        elseif(object)
        else {
            return $value;
        }
