This PHP error means that $result is not a valid queryResultObj.

The MapScript documentation should say that if nothing was found at
query location then queryUsingpoint() returns 0.  So your code should
check for that case:

         $result =$layer->queryusingpoint($point,MS_SINGLE,-1);
 
         if ( ! $result )
         {
           echo "Nothing found at click location";
         }
         else
         {
           echo("Result :$result->numresults"); //error!
           $shapendx = $queryres->next();
         ...
         }
