[Geojson] GeoJSON in php - proposed implementation

[Christoph Baudson]

Hello Pierre and David,

the Mapbender project I'm working on already uses GeoJSON to some 
extent, but the PHP code is more or less a project hack (we use it for 
converting GML2 into GeoJSON and vice versa). I'm not even sure it 
handles all available geometry types, but it was designed to handle 
multipolygons with enclaves, see a demo here

http://mapbender.wheregroup.com/mapbender_digitize/frames/login.php?&mb_user_myGui=gui_digitize&name=demo&password=demo

(You can fetch geometries by a WFS request, use the buttons on the upper 
right; if you have Firebug, you'll see that mod_wfs_result.php returns 
GeoJSON. You can also write geometries via WFS-T)

To make a long story short, I would also be interested and willing to 
collaborate.

Christoph
