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?
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...
