Well, I think it should work like this:
1) You call print-pretty (or some other function that produces some
2) The function checks whether or not there's a decoded metar. If so,
it will use that, otherwise it calls decode_metar()
3) decode_metar gets its METAR from get_metar()
4) get_metar uses the current METAR, if any, or else it tries to get
one by calling get_metar_from_db().
5) get_metar_from_db() uses the database, or calls
get_metar_from_web() if the METAR wasn't in the database or if it
was too old.
The idea with this is, that you should only call one function
(print_pretty()) - the rest is handled by lower-level functions. PHP
Weather is my first shot at object-oriented programming, so it might
not be the best solution, but on the other hand, I think it works
It's get_metar_from_web() that uses a lot of time to figure out,
whether or not the file is available. If anybody know how to quickly
check if a host is alive, then please tell me.
If you set 'always_use_db' to true, then get_metar_from_db() will use
the METAR is finds in the db, even if it's too old. If it can't find
the METAR, then it has to contact NOAA anyway.
