Does the above code work? If so, then it's very strange if you say
that the $data array is empty...

Did you use print_r() on $data?

You're looking for the lines that store values in the $decoded_metar
array.

That's a bit tricky as there can be several cloud-layers (up to
three). But look for 'cloud_layer1_coverage' or
'cloud_layer1_condition' for the first layer.

Entries 'visibility_miles' and 'visibility_km',

Yes, there isn't any documentation for this (except the source :-).

You should also take a look at the code found in CVS:

Individual files with diffs etc:

  http://cvs.sf.net/cgi-bin/viewcvs.cgi/phpweather/phpweather/

Snapshots:

  http://phpweather.sourceforge.net/downloads/

That code requires PHP version 4 and uses objects, but the decoding
works much like the code you've seen. The advantage is that the array
is documented, see this message:
