LSB
You can't reference the called class in the context of static inheritance. LSB adds a keyword that references the class that was initially called at runtime. Static methods or properties can be access only as part of a class itself.
class Car
{
public static $name = "Car";
public static function getName($self=false)
{
if ($self === true) return self::$name;
return static::$name; // Look Here
}
}
class Toyota extends Car
{
public static $name = "Toyota";
}
$car = new Toyota();
echo Car::$name; // Car
echo $car->name; // Notice:
// Accessing static property Toyota::$name as non static
echo $car->getName(); // Toyota
echo $car->getName(true); // Car
