[MS4W-Users] Problems with php-mapscript and postgis-layers from different databases

thanks a lot, I finally found my fault.

One of the many rows in my script was:
$map_file_layer_object->set('connection', $postgres_connection_string);

Because of that php-mapscript did not use the credentials from the 
mapfile, without that line everything works as expected.

Sorry for my noise...


I use MapServer 5.6.3 from "MS4W Base Installer v3.0 Beta 11" and am 
very grateful for the great software and your kind support!
