[mapserver-users] getExtent for Postgis Layer

[Sven Schroeter]

Hi, 
I try to get the extent of my layers using php mapscript:

$map= ms_newMapObj($mapfilepath.'\map.map');
$mylayer = $map->getLayerByName($getlayer);
$layerextent = $mylayer->getExtent();

echo $layerextent->minx." ".$layerextent->miny." ".$layerextent->maxx."
".$layerextent->maxy;

This works fine for layers with shapefiles, but there comes no result for my
postgis layers.
Any idea?

Sven
