Carlo,
I think the cache is refreshed each call of $layer-queryByPoint(point,
mode, buffer).
Remember to set the mode = MS_MULTIPLE to obtain more than one result,
the point is a $pointObj in GEOGRAPHIC coordinates, the buffer set to 0
get the default of the TOLERANCE (in pixels) of the mapfile, otherwise you
can specify in ground units a circle around the point for obtain the
results.
Look here:
http://mapserver.gis.umn.edu/docs/reference/phpmapscript-class
for a good guide about.
here a piece of code (it work):
$res = @$layer-queryByPoint($qpoint,MS_MULTIPLE,0);
if (@$layer-getNumResults() 0) {
$layer-open();
for ($i=0;$i$layer-getNumResults();$i++) {
$resCache = $layer-getResult($i);
$shape = $layer-getShape(-1,$resCache-shapeindex);
echo $shape-values['fieldname'].br;
// etc.
}
$layer-close();
}
ciao

Hi all.
I use PHPMapScritp with Mapserver 4.10 on Debian Etch.
I do a series of querybypoint, but the answer is always the first feature!
I think it could be a resultCacheMember problem. How can I free all
cache about previous query results?
New results of next query are appended to previous results or getResult
goes to a new set at any new query?
It is sufficient to close the queried layer ad to free the
$shp=getResult(...)?
Thank you very much.
Carlo
