[Rdfapi-php-interest] re:[rdfapi-php - Help] RE: RAP with PHP5

[Chris B. <bi...@ze...>]

Hi Josef,

the problem with moving the main code base to PHP 5 is that we would =
loose
backward compatibility with PHP 4. So before doing this step we really =
have
to consider the pros/cons.

RAP could gain from PHP 5:

- better integration of the iterators with the core PHP language =
constructs,
by replacing all "costom" interators with iterators with implement the =
PHP 5
iterator interface.
- better error handling using the PHP 5 exceptions instead of our =
current
home grown error handling.  =20
- speed improvements on database backed models by moving from ADO DB to =
PDO
(PHP Data Objects).
- maybe speed improvements by using PHP 5 new object features (???)

I think that RAP would only gain from the changes if they were applied
consistently over the whole code base, which would mean quite some work =
and
would require lots of testing/additional test cases afterwards.=20

I think it would be great to have a PHP 5 version of RAP, but the one =
who
touches this topic has to be aware of the amount of work a clean port =
would
require.
