sort() public method

If sorting by multiple fields, the first argument should be an array of field name (key) and order (value) pairs. This is useful in conjunction with {@link Expr::each()} for a {@link Expr::push()} operation. {@link Builder::sort()} should be used to sort the results of a query.

See also: http://docs.mongodb.org/manual/reference/operator/sort/

public sort ( array \| string $fieldName, integer \| string $order = null )
$fieldName	array \| string	Field name or array of field/order pairs
$order	integer \| string	Field order (if one field is specified)

    public function sort($fieldName, $order = null)
    {
        $fields = is_array($fieldName) ? $fieldName : [$fieldName => $order];
        foreach ($fields as $fieldName => $order) {
            if (is_string($order)) {
                $order = strtolower($order) === 'asc' ? 1 : -1;
            }
            $sort[$fieldName] = (int) $order;
        }
        return $this->operator('$sort', $sort);
    }
