How does it compare with GEOS's builtin PHP wrapper ? about geophp HOT 7 CLOSED

Hi strk,

If you have GEOS and you are creating a custom application I would definitely recommend using it instead of geoPHP. geoPHP contains a subset of the most important GEOS methods, but doesn't support most of the more advanced topological ones. geoPHP is meant to be used in applications that might be installed on shared hosts etc. where GEOS is not available.

However, if geoPHP detects that GEOS is installed, it will automatically wrap itself around it and start using GEOS. See here for more details on how this works: https://github.com/phayes/geoPHP/wiki/GEOS

Oh, the one reason you may want to use geoPHP instead of GEOS (or even better,with GEOS) is all the awesome adapters we have (wkt, wkb, geoRSS, KML, GPX).

And I just realized that the big comment I wrote to you got eaten by the internet. Will post again...

Neat ! Thank you for the overview.

I've added geoPHP on the list of GEOS users:
http://trac.osgeo.org/geos/wiki/Applications

First user of the PHP API I know of :)

Thanks!

One useful way you could use geoPHP with GEOS that I just thought of just this moment is to only use geoPHP as a format parser. For example:

$GEOS_geom = geoPHP::load("<georss:polygon>10 23 45 53 12 10 23</georss:polygon>",'georss')->geos();

This should allow you to use geoPHP to load GEOS geometries from geoRSS, GPX, KML and GeoJSON (and addresses via google geocode). Equally, here an example of using geoPHP to output GEOSGeometry into kml:

$kml = geoPHP::geosToGeometry($GEOS_geom)->out('kml');

Just a thought. I should add this to the wiki. :-)

Just one more thought, given that it sounds like you are interested in knowing if your GEOS PHP bindings are being used: GeoPHP is used pretty extensively in Drupal (it's a prerequisite for many of the more powerful mapping modules). I know that many people in Drupal-mapping-land have installed GEOS because of the performance improvements you get when using it along-side geoPHP. FYI. :-)

Drupal was actually my main target for writing the GEOS PHP bindings,
so I'm glad it's finally used there :)
