Hi all,
=20
We are developing a sample site with Mapserver 4.2 and PHP mapscript.
We=92d like to add some custom functions that require that we can
determine at run time certain aspects of the layers being published
through the map file, for example what type of data the layer is (e.g.
raster, shapefile), what its geometry type is (e.g. polygon, line), etc.
We had been thinking we=92d parse the map file on initial load, and =
access
it programmatically from a set of arrays; but as the map file structure
is not XML based there isn=92t an easy way of parsing the map file
directly. Are there any built-in functions available to allow us to do
this?
=20
Thanks for any help you can provide.
