layer order

[SUBSCRIBE MAPSERVER-USERS Nuri]

I would like that layers in my map appeared in a concret order.

On the top the text one, then the symbol one, then the shapes one and the
raster on the back.

How can I do it?

This is my training map:

    # Alternatively, you can specify an EPSG code.
