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.

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)
