[OSGeo-Discuss] Transform from winkel_ii meters to mercator web

In advance please forgive me for not using the correct jargon, or not
posting in the right section.
I have a database with boudingboxes for objects on a map in meters for the
Winkel II projection. I want to read these boudingboxes and transform them
to Mercator Web to use them with OpenLayers.
I noticed that in proj4 the winkel_ii transform functions are available, but
not in proj4js.
My plan would be to install a proj4 package on my linux server and call the
transformation function from php code.
My question is: will this work? Can I call proj4 functions from php. If so,
which function(s) would I use? Can you give me an example how to do that
I have now testet with cs2cs.exe and tried:
cs2cs.exe +proj=wink2 +datum=WGS84 +to +proj=latlon +datum=WGS84
with coordinates: 390423.776 5958130.269
there was no result, when I try the same with +proj=wink1 I do get result. I
figure this is because there is no inverse calculation available for wink2,
but of course I am not sure.
Thanks a lot for your time!
