Deleting from a shapefile

[Antonio Iandolo]

Hi all,
I have a shapefile where I append points (permanently, not inline) using
the php-mapscript addPoint method.

My question is: is there a way to permanently delete points from such a
shapefile? I could create a new temporary shapefile with all the same
points except the deleted one, but it doesn't seem to me a great
solution...

Thanks in advance,
Antonio
