project Method is missing about geophp HOT 5 CLOSED

Hi Karsten,

Oh you are correct. We have the "project" method in the API documentation, but it's not implemented in code! Whoops! A pull request would be great.

OK, this is now fixed

@kviolka Dude, how do you project? Could you give me some sample code, I am obviously dumb...

I have something like:

$point1 = new \Point(10, 12);
$point2 = new \Point(12, 10);

How to get distance in meters? How to invoke properly project() method? Thanks!

If you are using geographical coordinates (lat, lon) then greatCircleLength() is your friend:

$line = new LineString([new Point(10, 12), new Point(12, 10)]);
echo $line->greatCircleLength();    // 311971.11435993 meters
echo $line->length();               // 2.828427 degree

@BathoryPeter DUDE! You are awesome! Thanks!

How about calculating shortest distance between two, per example, polygons? Is that possible? How to do that?

BTW, your recipe, as well as my second question -> I think that it should be part of the documentation, it is quite common...
