Hello to everybody. I saw that is a "tradition" that new members do here a very short presentation. So I start saying that my native language is not english so I apoligize for gramatical and exprimal mistakes.

I am relative new in php and I search for information in this domain. A problem that i have is with the OOP. I dont know how to use the "::" operator.I have some big books with php but neither one covers this operator. I saw in some joomla code that it's use without creating an object. The "->" is in every book. Thanks
