[mapserver-dev] PHP Mapscript - Differences between whichShape and queryByShape

[Nicol Hermann]

Hello Devs,

i have a question concerning the function of the method
$layer->whichShapes($Map->extent);
of PHP mapscript.
As far as i understand the documentation
(http://mapserver.org/mapscript/php/) the method returns all shapes
within a given area (in this case $Map->extent).
I wonder what are the differences to the method
$layer->queryByShape( $shpobj );
$shpobj is defined as 'MS_SHAPE_POLYGON' and is constructed with the
same values like $Map->extent
To my understanding both methods should return the same number of query
results.
Is this assumption correct?
Many thanks for your assistance.

best regards
Nicol
