[mapserver-users] Point in polygon

[truongpm]

Hi list,

I have a problem with defined a point is in which polygon. For example, a
map have 2 layer: commune-polygon; park - point.
I want to layout color of polygon (each commune) depend on amount of point
in this polygon.

I done with query polygon from mySQL database, layout its color base on an
attribute in database.

My question is that how could i know which polygon that point inside???

Thanks for your attentions and sorry about my language skills.
