[Mapserver-users] How do i display only the points i want? (PHP/Mapscript)

[Ed Martin]

i'm using php mapscript and can't figure out how i get it to only 
display the points i want, i have a shapefile that has all the towns in 
the US (they are all points) and i have the index of every point i want 
to display, i can't figure out how to do this

so basically what do i do to first make it so that by default the 
points don't show up on the map, but when i give the index of one of 
the points it shows up

i looked at the php mapscript class reference stuff and can't find 
anything that looks like it will do this
