The point isn't to echo a string, it is to demonstrate that the static method in the base class is aware of the name of the class on which the method was invoked. Late Static Binding is useful in lots of situations, but not being available in PHP before 5.3 this "fake" approach allows you to do something similar. A practical example would be a Singleton base class with a static getInstance method, that returns an instance of an implementing base class. I hope that explains it a little better! Thanks, Ben Hi Robert,

Do you have any idea what you are talking about? How is this fake LSB useful in any way? Can you give us an example? Why don't you use # echo "class0"; # echo "class1"; # echo "class2" ; That's much more easier. Can you show us an example usage of this getName() method? How can you even call this a fake LSB? Do you have any idea what you are talking about? How is this fake LSB useful in any way? Can you give us an example? Why don’t you use

# echo “class0″;
# echo “class1″;
# echo “class2″ ;

That’s much more easier. Can you show us an example usage of this getName() method?

The example is there to show how we can achieve what we want in PHP5.3 The example before that is how I propose to "fake" LSB in PHP pre 5.3. Sorry if that wasn't clear enough. Thanks, Ben Hi Daniel,
