I think it's called a database. The fields are outputtype, key, and
text to output, with an index on outputtype + key, then you do
something like this:
select OutputText from TranslateTable where OutputType = 'wml'
and key = 'authorstart';
I wonder how many of these you really have. If on each script
invocation you will be looking up many of them (dozens or hundreds) it
might be more efficient to load all the ones for the outputtype you are
using into a PHP array at the start, whether that's in a hard-coded
array or loaded from the database. If you're only looking up a couple
then a separate database lookup for each one is probably more
efficient.
Incidentally I would say this is not a templating problem. It's simply
a translation or lookup problem.
