Extend existing fields and self::

Hi!

I wanted to extend some field behaviour and my first idea was extending from it. Nevertheless, I couldn´t, because as long as I saw, there were some checks based on self:: function that didn´t work properly because how "self::" works. I think that some of this behaviour could be done with "$this->", that won´t generate inheritance problems. I´m correct?

Hello

self::

was used for PHP 5.2 or PHP 5.3 compatibility
i don't remember now



because of it,
you will have to copy ALL functions and rewrite their code


effectively the self::
- partially damages heritage and turn polumorfism "off"


in future we will replace it by $this

hhmm i meant we will replace

self::

with

static::

that allow heritage and polymorfism to work more properly,
that is when we stop PHP 5.2, 5.3 support
