Why I can't read static variables of a child class, even so the variable is protected or public?
Here's what I tried:
class A {
protected static $foo = "bar";
}
class B {
public function readFoo() {
return self::$foo;
}
}
When now calling B::readFoo, I get the following error:
var_dump((new B())->readFoo());
PHP Fatal error: Access to undeclared static property: B::$foo in php shell code on line 1
PHP Stack trace:
PHP 1. {main}() php shell code:0
PHP 2. B->readFoo() php shell code:1
Fatal error: Access to undeclared static property: B::$foo in php shell
code on line 1
Call Stack:

86.2666 231352 2. B->readFoo() php shell code:1
