Hello world,
il am using php/mapscript with mapserver 4.0 on NT plateform.

i would like to perform a rect query on a shape layer containing =
ploygons.
I obtain 605 result with oResults->getNumResults()
then  i loop through these results in order to get each point and lines =
in the shape
Everything is good till the "for" process reach the 12th record.

Whe i try to use two layers to examine, with (3 results on the first and =
605 for the second)
The first layer is well computed but only the 8th with  the second query =
(on the second layer)

that's to say only 12 shapes are computed.
I hope this is understandable!!!
thanks
fx
