PHP Scope Resolution Operator (::)PHP original manual for Scope Resolution Operator (::) [ show | php.net ]Scope Resolution Operator (::)The Scope Resolution Operator (also called Paamayim Nekudotayim) or in simpler terms, the double colon, is a token that allows access to static, constant, and overridden members or methods of a class. When referencing these items from outside the class definition, use the name of the class. As of PHP 5.3.0, it's possible to reference the class using a variable. The variable's value can not be a keyword (e.g. self, parent and static). Paamayim Nekudotayim would, at first, seem like a strange choice for naming a double-colon. However, while writing the Zend Engine 0.5 (which powers PHP 3), that's what the Zend team decided to call it. It actually does mean double-colon - in Hebrew! Example #1 :: from outside the class definition
<?php Two special keywords self and parent are used to access members or methods from inside the class definition. Example #2 :: from inside the class definition
<?php When an extending class overrides the parents definition of a method, PHP will not call the parent's method. It's up to the extended class on whether or not the parent's method is called. This also applies to Constructors and Destructors, Overloading, and Magic method definitions. Example #3 Calling a parent's method
