Hi list,

I am fighting in the moment for clear thoughts in my dusty brain. Perhaps 
somebody could help me out...

I have a bundle of national statistical data sets which cover the whole 
world (GDP, Arable Land, etc...). I serve them via MapScript as Shapefiles 
to my map-module, but at the same time in another non-map module as raw 
values via my MySQL database.

Now I want to enable the user to pre-select a region like Europe or Africa. 
This cut-out should then not only be displayed as a map, but be available 
as a zipped shapefile for download.

I read through the posts of the list and found the "ms_newShapeFileObj" 
command as a possible solution. I would then probably query the global data 
set and "paste" the records into the new -regional- shapefile. Another 
possibility would perhaps be to copy the original file and just delete the 
unnecessary entries. Or I would have already created the regional files, 
but without the data, and would then fill them via the MySQL database.

Does anyone have experiences with zipping files in PHP?

Any hints, ideas and code-examples are very much appreciated.

Best wishes,

Stefan

P.S.: I am using MapScript 3.5, PHP, Apache, NT/Linux.
