QueryByRect problem in PHPmapscript

[Bill Thoen]

I'm trying to understand how to do querying via PHP mapscript, and I 
don't understand the results I'm getting. Basically I'm querying a 
polygon layer of US States with a rectangle that intersects 8 states in 
the upper midwest. It fully encloses two of these. The following script 
seems to find only one result and it says the shapeindex is 42. Now I 
know this is the answer to the meaning of life, the universe and 
everything, but how do I use this to get a list of the state names that 
were found (and why is it only returning 1 found?)

What I want to do eventually is display these states on the map in a 
highlighting color to show they were selected. If I'm going about this 
all wrong, could somebody clue me in?

   $rect = ms_newRectObj();
   $rect->setextent(-50000, -50000, 50000, 50000);
   $lyr = $map->getLayer(1);  // states layer
   $results = $lyr->queryByRect($rect);
   if ($results == MS_FAILURE) {
      echo "Nothing found.<br />";
   } else {
      echo "Found " . $lyr->getNumResults()."<br />";
      for ($i=0; $i<$lyr->getNumResults(); $i++) {
         $rcache = $lyr->getResult($i);
         echo "   shapeindex: ".$rcache->shapeindex;
      }
   }
   $rect->free();
