what is the :: double colon used for

[Anon]

I saw a piece of code using double colons for some kind of class referencing. Can someone tell me more? I have not see anything in any docs about. If I could be directed to some info that would be great!

I believe it's used in classes. I'm not positive though!

The double colon's allow you to reference a function of a class without actually creating an instance of the class. The syntax is:

classname::functioname();

Note, however, that if any references in the function are made to $this, the call will fail--you will need to create an instance of the class to use the function. Hope that helps.
