Domain Driven Design

• The Value Object pattern is also a building block
  of Domain-Driven Design. In practice, it
  represents an object which is similar to a
  primitive type, but should be modelled after the
  domain's business rules.
• This is a reason why we may use objects even if
  we already have basic, old procedural types.

3
Identity vs. equality

• The definition of a Value Object, that authorize
  if we can apply the pattern to a class, the
  equality of two Value Objects is not based on
  identity, but on their content. An example of
  PHP built-in Value Object is the ArrayObject
  class, which is the object-oriented equivalent of
  an array. Two Array Objects are same if they
  contain the equal elements, not if they are the
  same identical object.

4
Scalars, as Object

• Value Objects also for basic values like strings
  and integers, while PHP limits itself to the
  ArrayObject and Date classes. Another example of
  a typical Value Object implements is the Money
  class.
• Continuing with the Date example, we usually
  don't care if two Date objects are the same, but
  we care instead to know if they had the exact
  identical timestamp in their internals
