Adding shapefile dynamically with php_mapscript 4.4.2

[Stephen Woodbridge]

Jacob,

The way I do this is to create a normal in the mapfile with the STATUS 
OFF and no DATA statement. Then in mapscript all I do it set the STATUS 
ON and assign the path to the DATA like you are doing below.

It is MUCH easier to create a template layer in the mapfile and then 
manipulate it, rather than creating the whole thing from scratch.

YMMV,
