coordinate systems transformations

[Mauricio Leon]

Thanks again Gregor,
I am trying to run your example code in php but I have the follwing error:

"Fatal error: [MapServer Error]: msProcessProjection(): major axis or
radius = 0 or not given in C:\ms4w\apps\et_map\htdocs\map_main.php on line
106"

where 106 is this:

$projInObj  = ms_newprojectionobj("proj=latlong");

the error creating the projection object does not occur when the projection
info is give as an epsg code:

$projInObj =  ms_newprojectionobj("init=epsg:26759");

does not yield error.

Any ideas?
