Thanks for the compliments - my head is now a bit bigger :-)
I thought 0 deg
o "$degrees degrees is roughly $compdir on the compass\n";
}
Yeah, I don't know what "east of northeast" is, so I just labeled it
"NEE" :)
Great thinking though. You still get the prize on this one.

Hi,
Alternatively, try :-
$Compass = array('West', 'North Westerly', 'North', 'North Easterly',
'East', 'South Easterly', 'South',
'South Westerly');
print $Compass[round($Degrees / 45)] . "\n";
This can be expanded easily by adding 'North North W

The cleanest looking multiple "if" scenario is to use a "Switch" statement.
Unfortunately I don't believe PHP's "switch" will do varied conditions, only equality
statements:
$j = 5;
switch ($j) {
case "< 6":
echo "first";
break;
case <6:
echo "second";
break;
case 5

I have to write a little function to convert a direction from degrees
to a compass -type heading. 0 = West. 90 = North. E.g.:
Something like this... it'll account for >360 degrees, too. No different
that a bunch of IF statements, though...

In some other languages, you could put your range of values in the "case" statements,
but not PHP I guess.
I think in this case, you're stuck with a bunch of if/elseif statements. Only 16 of
them though, right? :)

I have to write a little function to convert a direction from degrees
to a compass -type heading. 0 = West. 90 = North. E.g.:
from:
135 degrees
to:
NW
Now, I was planning to write a series of if statements to evaluate e.g.,
if ($heading_degrees < 112.5 && $heading_degrees > 67.5) {
$headi
