storing translations

[cold]

-translations for different languages are stored in .ini files.
-the choosen language is stored in a $session['lang'] variable.
-for every file accessed i load the .ini file representing the $session['lang'] and store it in the _strings() array.and use those strings for substitution.

The Question: is it better if i store the translated text once in a similar $_session variable for use during the whole session.or better to create a new instance of the i18n class and reload the .ini translation file for every new page the user access?

I would say that it is better to load the file for every page load. What if you have lots of users, then you would get pretty large sessions.

Even better would be to have translations for each page in a separate file, then you don't need to load more than what is needed on the page.

But best is probably to store it in a database, it will save you from troubles in the future, if you for example have a page that is only partly translated or only some pages are translated.
