scale and query problems

[Robert Ofarrell]

A couple of problems that I have run into when using MapScript with PHP3.

1. When doing a query on a map with multiple layers, the result of a
msqueryUsingPoint() only returns the shapes in the first two layers and
seems to ignore the other layers on the map.  I have a nice tolerance so
that all the layers have some shape where I click but only the first two
layers respond.

2. When I am trying to find the scale that I am currently at on the map
when zooming, the $map->scale returns -1.

Any help would be greatly appreciated.
