PHP version of the ASP.NET/C# property attribute class

Question

Is there such a thing?

I would like to do something similar in PHP, but cannot figure out how to do this from PHP docs:

public class User : ValidationBase
{  
  [NotNullOrEmpty(Message = "Please enter a user name.")] 
  public string UserName { get; set; } 
}

I am looking for the PHP equivalent of the ASP.NET/C# property attribute, which in the example above is indicated by a line [NotNullOrEmpty(Message = "Please enter a user name.")]above the property declaration.
