Member variables and methods can now be declared static, allowing them to be called from outside an instance of the object

<?php
    class coggeshall {

        static $myvar = 10;
        
        static static_func() { /* ... */ }

        function another_func() { /* ... */ }
    }

    coggeshall::$myvar = 20;
    coggeshall::static_func();
    
?>
