I was trying to generate a localized date string with strftime, the placeholder I use is %x. The language/locale is setlocale(LC_ALL, array('jp','japanese')), however neither locale was available so it generated a string with improper characters. I then installed the ja_JP.utf8 locale and specified that as the first element in the array and the date formatting issue I had was resolved.
My question is, should I always rely on locales being installed? I’m aware of how to install them on boxes I have root access to, but what if I don’t have access?
I believe Zend_Locale and Zend_Translate do not rely on setlocale at all but somehow do it internally, which gives me the impression that it isn’t practically feasible for enterprise level applications.
I know I could probably use Zend_Locale and Zend_Translate in my application but it also needs to support PHP4, at least for another year which is why I can’t solely rely upon those.
If my examination of setlocale() is correct, the answer is: No and no. The range of installed locales varies, as does their name, and the availability of a certain locale ultimately cannot be predicted with total certainty.
