queryByPoint Problem

> The problem is, I don't get the expected results.  I very rarely get any features returned from the first layer, and I always get results from the second layer, even if there isn't a feature at the click point.  I have verified that coordinates being calculated are correct.  Both layers have templates defined in the mapfile.

When I click on a gap between polygons with a buffer of 0, I should get no results, but I always get one of the polygons close by.



Could part of the problem is that you set the buffer to 0? That means 
that the buffer defaults to whatever tolerance you have set in the map 
file. From the phpmapscript reference:

"Passing buffer <=0 defaults to tolerances set in the map file (in pixels)"
