Very nice solution, Dave. I like simple, elegant and effective
solutions like this. I was wracking my brain yesterday to come up with
something like this, but my brain wasn't working. Hah. Good job!
I think your compass directions are a bit off though.hah. West
shouldn't be 0 degrees, it should be 270 normally (unless someone's
using a compass system that I'm not familiar with).
Here's a variation of your script that displays all 360 degrees (for
validation purposes):
$compass =
array("N","NNE","NE","NEE","E","SEE","SE","SSE","S","SSW","SW","SWW","W"
,"NWW","NW","NNW");
for ($degrees=0;$degrees<360;$degrees++) {
$compcount = round($degrees / 22.5);
$compdir = $compass[$compcount];
echo "$degrees degrees is roughly $compdir on the compass<br>\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.
