Hi Dieter,
I also just used MS4W's PHP (PHP version 8.3.9) to call the setOpacity()
function, to update the layer's opacity, such as:
$oPolyLayer->setOpacity(40);
(see sample script at https://ms4w.com/trac/wiki/SWIGMapScriptOpacity )

Hi Dieter,
It could be possible that your MapServer installation was compiled with
Pixman library support enabled in MapServer, which unfortunately causes
a known bug where opacity does not work (see
https://github.com/MapServer/MapServer/issues/5343 ). I believe we
should completely remove Pixman support from MapServer in a future
release, as so many users hit this issue each year.
In other words, make sure that you set -DWITH_PIXMAN=0 when compiling
MapServer from source.
PS. I actually used the small mapfile included in that ticket, for
testing now with today's MapServer 8.3-dev on MS4W 5, on Windows, and
successfully generated a proper map image (with opacity) with map2img.
thanks,
