You have to ask yourself: "Am I targeting the problem with the adequated approach?"
self::
and static::
do two different things. For instance self::
or __CLASS__
are references to the current class, so defined in certain scope it will NOT suffice the need of static calling on forward.
What will happen on inheritance?
class A {
public static function className(){
echo __CLASS__;
}
public static function test(){
self::className();
}
}
class B extends A{
public static function className(){
echo __CLASS__;
}
}
B::test();
This will print
A
In the other hand with static::
It has the expected behaviour
class A {
public static function className(){
echo __CLASS__;
}
public static function test(){
static::className();
}
}
class B extends A{
public static function className(){
echo __CLASS__;
}
}
B::test();
This will print
B
That is called late static binding in PHP 5.3.0. It solves the limitation of calling the class that was referenced at runtime.
With that in mind I think you can now see and solve the problem adequately. If you are inheriting several static members and need access to the parent and child members self::
will not suffice.
