How can protected property of a class be visible from a static method in PHP?
class, oop, php, visibility
Solution
In PHP 5.3, a new feature called late static bindings was added – and this can help us get the polymorphic behavior that may be preferable in this situation. In simplest terms, late static bindings means that a call to a static function that is inherited will “bind” to the calling class at runtime. So, if we use late static binding it would mean that when we make a call to “test::oo();”, then the oo() function in the test class will be called.after that you return $instance->a; static keyword allows the function to bind to the calling class at runtime.so if you use static then whatever access modifier(private,public,protected) you use it's just meaning less...

Problem
I understand OOP. What I understand so far is that private and protected cannot be referenced from outside the class using $this->blah notation. If that is correct, how can the following code work? ``` <?php class test { protected $a = "b"; public static function oo(){ $instance = new static(); echo $instance->a; } } test::oo(); ``` Gives me an output of b! Now, how in Lord's name can that happen?
