Have a look at the delivered PHP scripts in your Geomoose htdocs/php directory (especially the end of select.php), and at
<a href="http://www.geomoose.org/docs/services.html">http://www.geomoose.org/docs/services.html</a><br>
<br>
Basically you have your PHP send GeoMOOSE API calls (as JavaScript), wrapped in the very excellent GeoMOOSE Service Communication Protocol, specifically a
<br>
<br>
GeoMOOSE.refreshLayers("my_mapsource/mylayer")<br>
<br>
I can't seem to find a link to the API on the GeoMoose site, but you can have a look at
<a href="http://www.geomoose.org/trunk/api/files/geomoose-js.html">http://www.geomoose.org/trunk/api/files/geomoose-js.html</a><br>
