[Mapserver-users] more syntax questions

[pkishor_98]

well, dunno if this is the right forum or not, but since I am a member of only this 
forum... here goes.

Why does one need to do $layerObj->queryByShape($mapObj,$shapeObj) when 
$layerObj->queryByShape($shapeObj) should suffice... after all, the layerObj has 
been derived from the mapObj already... or is it that there might be more than one 
mapObj in the same scope? Same argument applies to $layerObj-
>queryByRect(mapObj,rectObj) and many other such methods.

I am not nitpicking -- just trying to figure out intuitively how to put together a map 
using the syntax that mapscript offers. Let me know if there is a better forum for this 
kind of discussion.

Thanks,
