Hi,
I think you could use the ProjectionObj in Mapscript to convert your points:
http://mapserver.gis.umn.edu/docs/reference/phpmapscript-class/classes/projectionobj
Copied/pasted from the above link::
Creates a projection object based on the projection string passed as
argument.
Eg : $projInObj = ms_newprojectionobj("proj=latlong") will create a
geographic projection class.
Eg of usage : the following example will convert a lat/long point to an
LCC projection :
$projInObj = ms_newprojectionobj("proj=latlong");
$projOutObj = ms_newprojectionobj("proj=lcc,ellps=GRS80,lat_0=49,".
"lon_0=-95,lat_1=49,lat_2=77");
$poPoint = ms_newpointobj();
$poPoint->setXY(-92.0, 62.0);
$poPoint->project($projInObj, $projOutObj);
So replace the parameters according to your projections

Hello,
If your EXTENT are degrees (-180 -90 180 90), so your UNITS should be
DD
and not METERS and this should match your map projection setting.
And if your wms server is Danmark only, try focusing on Danmark, not
the
world!
Didn't found any epsg:54004, is it standard ?

Hi Marc
Your input helped me further - now I can actually generate the map with
the 54004 (Mercator) projection).
However I have a bit of a problem.
In my PHP mapscript I can only display something by using the
coordinates in meters as you supplied it:
$gpoMap = ms_newMapObj("wmsmmap.map");
$gpoMap->setExtent(868292.03, 7135562.57, 1447153.38, 7931049.58);
However I would like to set the extent using degrees - i.e:
$gpoMap->setExtent(7.8, 54, 13, 58);
How would I do this?
Alternativly how could I convert my degrees to meters as you supplied
it?
Best regards,
Michael
