Hello,

Disregard previous question, I had a small error in the way I was querying 
my database.  For the record the following works to change the symbol 
dynamically.

Dan

 >>>Map File<<<

symbolset "./symbols/symbols.list"

...

LAYER
   name 'mylayer'
   type POINT
   class
     name 'symbol'
     style
       symbol 'symbol_1'
     end
   end
END

 >>>symbols.list<<<

SYMBOL
   name'symbol_1'
   type PIXMAP
   image '..\graphics\symbol_1.gif'
END

SYMBOL
   name'symbol_2'
   type PIXMAP
   image '..\graphics\symbol_2.gif'
END

 >>>PHP Mapscript<<<

$layer = $map->getLayerByName('myLayer');
$symbolClass = $layer->getClass(0);
$symbolStyle = $symbolClass->getStyle(0);
$symbolStyle->set('symbol', 1);
