[mapserver-users] List all symbols on PHP ms_map_object

[Cristiano Sumariva]

I want read all symbols available in a mapfile for listing.

Documentation says that I can request symbol references by calling
ms_map_obj->getSymbolById( id ).

What is not well defined on documentation is if those id are numbered from
zero to n-1 symbol.
so I can loop over the list.
