 Static classes are a well known construct for utility classes or stateless abstraction. C# for example has an class System.Environment to access command line options, the current directory, the name of the machine where the program is running and so on. In PHP the current practice is to use an abstract class with static methods. Static classes are a well known construct for utility classes or stateless abstraction.

 Static classes can act as utility containers. For such utility containers or for more complex static inheritance, static classes are a helpful tool.
