Point In Polygon [php]

rivux · 03-30-2006, 09:55 AM

Ive seen several c/c++ algorithms for finding out whether a point is within a polygon but Ive yet to find any php implementations of this. If anyone has some sample code or could point me in the right direction I would appreciate it.

Never needed anything like that before so I can't really help. Cant you take the formula from the c/c++ algorithms and write it up in php?

good luck with finding it out im curious to know what your working on.

Someone from another board pointed me in the right directory. With a few mods I was able to get this code to work:
