Hi.

Sorry I can't tell you the exact way because I never tried but I think 
you have to:

- create a pointobj with the wanted coordinate
(http://mapserver.gis.umn.edu/doc40/phpmapscript-class-guide.html#pointobj)

- create a shapeobj and add your pointobj
(http://mapserver.gis.umn.edu/doc40/phpmapscript-class-guide.html#ShapeObj)

- add the shapeobj to a layer
(http://mapserver.gis.umn.edu/doc40/phpmapscript-class-guide.html#LayerObj)
or add it to new shapfileobj
(http://mapserver.gis.umn.edu/doc40/phpmapscript-class-guide.html#shapefileObj)
and then add it to a layer

Regards,
Norbert
