Static classes and static variable usage classes in php Analyzed the difference between static classes and static variable usage classes in php, Create the object $object = new Class(), and then use "->" to call: $object->attribute/function, the premise is The variable/method is accessible. Directly call the class method: class::attribute/function, whether it is static or non-static , static static: declare the class member or method as static, and it does not need to be instantiated For direct access to a class, static members (except static methods) cannot be accessed through an object. Static members belong to the class and do not belong to any object instance, but object instances of the class can be shared.
