Hi,

When exactly do we use

::

So for example

static::$db_table

User::find_all();

Hi Konrad,

I asked the question as well to a developer at some point and they explained to me that sometimes you have functions defined as private in your Parent class, that you don't want to pass on to the instantiated Child objects. In that case, if you still want to use the private function, you would use Parent::function().

But in all honesty, I've not yet used this kind of method myself apart from using PDO functions such as PDO::PARAM_STR.

Kindly,

N8
