Bug description:"static" scope resolution operator
Description:
------------
It's stated in
http://php.net/manual/en/language.oop5.paamayim-nekudotayim.php
that "Two
special keywords _self_ and _parent_ are used to access properties or
methods from inside the class definition", but there's also 3rd keyword
which is not mentioned - "static".
Test script:
---------------
<?php
header('content-type: text/plain');
class ParentClass {
const property = 'parent';
public function getPropertySelf() {
// use 'property' const of ParentClass
return self::property;
}
public function getPropertyStatic() {
// use 'property' const of called class
return static::property;
}
}
class ChildClass extends ParentClass {
const property = 'child';
}
$obj = new ChildClass();
var_dump($obj->getPropertySelf()); // string(6) "parent"
var_dump($obj->getPropertyStatic()); // string(5) "child"
