Using PHP Gettext Extension vs PHP Arrays in Multilingual Websites?

Question

So far the only 2 good things that I\'ve seen about using gettext instead of arrays is that I don\'t have to create the \"greeting\" \"sub-array\" (or whatever its called).

Answer 1

Using GNU gettext you get support for placeholders like with printf and international plural forms. Placeholders order can be changed in translation or skipped.

Example from PHP documentation:

Another pro is that you can use standard tools for terminology management, translations memory and machine translation as pointed by @middus.

For shared environments there is a great php-gettext library from Danilo Segan.
