union return null

[Boka]

Hi,
I ran the following code example and I keep having null in $combined_poly var...
is there something that I'm doing wrong?
sorry to bother
ciao

            $poly1 = \geoPHP::load('POLYGON((30 10,10 20,20 40,40 40,30 10))','wkt');
            $poly2 = \geoPHP::load('POLYGON((35 10,10 20,15 40,45 45,35 10),(20 30, 35 35, 30 20, 20 30))','wkt');
            $combined_poly = $poly1->union($poly2);
            $kml = $combined_poly->out('kml');

union requires the native Geos module with PHP bindings compiled

Thanks for the tip! Will be good to throw an exception of missing Geos module, instead of silently returning null.

You may give a try to my fork. It also throws exception if Geos is missing.

See the union method:

Wow, cool, thanks @BathoryPeter! Maybe create a PR to main repo with this your exception enhancement?

I had a pull request: #125.
