The mapObj's getNumSymbols() and getSymbolObjectById() methods should 
allow you to do something like this (untested):


   $numsymbols = $map->getNumSymbols();

   # Start looping at 1 since symbol 0 is the default symbol
   for ($id=1; $id < $numsymbols; $id++)
   {
     $symbol = $map->getSymbolObjectById($id);
     # Do something with $symbol here... see the symbolObj class docs...
   }
