Thanks for the suggests.
I will have to make some tests to see what will happen, especially how fast.
I will post after that my opinion.
Regards,
Andy.

Hi, We have a big multilanguage project. For a while we used gettext to
translate the pages, but we gave up on this because of many problems. Out
solution is to create a file for each language which includes the
"label" definitions. for ex: define("LABEL1", "label 1");
define("LABEL2", "label 2");
etc...
Now, one of this file can contain more than 2000 defines and we make a
calculation that we will reach 8000 in 2 years. I made some
testing(generated many label) in including these files into the project
it seemed to work fine. I don't know how php handles these defines(memory
usage, CPU etc) so the question is: how much affects the performace the
inclusion of a lot of defines???
creating constants is _very_ slow...
if gettext is too much hassle (I can understand that ;-) it's a pity, but
you have the alternative of
using an array:
$Lang = array(
'LABEL1' => 'hallo!',
// etc
);
OR install APC and write a routine that uses apc_define_constants() (not
on every request obviously -
well it will becomne obvious when you read up on apc and that function in
particular) and
apc_load_constants(). which means you can still use define() and not
suffer the speed hit - although
be prepared to use up a little RAM :-).
note that although this means you will use the constants in your app the
definition of the LABEL=>text pairs
will be an array if you go the APC route.
http://php.net/apc
ps - the info on constants and apc is regurgitation of advice/info coming
direct from Rasmus.
I have never tested it, I assume he knows what he's talking about
(otherwise why would he bother to
write apc_load_constants()/apc_define_constants()?)
pps - use single quotes for the __minimal__ decrease in processing that
the skipping of
string interpolation causes.
