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 ..........................pg -- Pietro Giannini Bytewise srl - Area GIS 41°50'38.58"N 12°29'13.39"E On Lun, Aprile 21, 2008 13:20, Carlo Pelliconi wrote: > 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.
