title: What is an example of a Value Object in PHP?
body: <p>I have read plenty of C# examples of Value Objects, and I understand that it is an "object" that is identified by it's values. If a value changes, the object is "new".</p>
  
  <p>However, that doesn't seem to make sense when it comes to PHP...either that, or I'm just not making the connection.</p>
  
  <p>Is a Value Object just a string?</p>
