php-mapscript: abnormal death

[Bart van den Eijnden]

Hi Mark,

Have you defined an outputformat in your MAP file (or dynamically in php)?

http://mapserver.gis.umn.edu/doc44/mapfile-reference.html#outputformat

eg for png 8 bits:

OUTPUTFORMAT
   NAME png
   DRIVER "GD/PNG"
   MIMETYPE "image/png"
   IMAGEMODE PC256
   EXTENSION "png"
END

Maybe you even need to set it (I don't know if this is necessary if there
is only 1 output format though ...):

$map->selectOutputFormat('png');

Hope this helps.

Best regards,
Bart
