The expression $sqls of type array is implicitly converted to a boolean; are you sure this is intended? If so, consider using empty($expr) instead to make it clear that you intend to check for an array without elements.

			throw new \LogicException('The "' . basename($migration_file) . '" migration contains no SQL statements.');
