Ah, I see. That's my mistake re: gszQueryLayers being names and not ids.
 
Since I was using the same information somewhere else in my code and wasn't 
using the highlighting then anyway, I had changed that variable to pass in the 
actual layer names instead.

The original code still didn't work properly though; $nCount was undefined and 
I believe the explode syntax was incorrect (can't remember).

So, really the first part of the code should be as follows:
    if ( $szQueryLayers != "?" )
    {
        // get array of layers
        $aszLayers = explode(",", $szQueryLayers );

        // loop and get the name of each layer
        for ( $i=count($aszLayers)-1; $i>-1; $i-- )
        {
            // get layer
            $oLayer = $oMap->getLayer( $aszLayers[$i] );

            if ( $oLayer->type == MS_LAYER_RASTER ){
                // remove the layer from the query
                unset($aszLayers[$i]); 
            } else {
                // update array to be name
                $aszLayers[$i] = $oLayer->name;
            }
        }
    }

Or, alternatively, it could be written to handle being passed an array of 
indices or layer names (which is how I'll have to write my version of 
drawmap.php).
Cheers,
jtm
