Hi,

	I have been looking through the Mapscript API and can't find what I'm 
looking for.  I'm just asking for help with a tip as to where to look. 
I'm trying to display the results of my query.

++++++++++++++ BEGIN CODE ++++++++++++++++++
<?php
dl('php_mapscript.dll');

list($layername, $field) = split(",", $_GET['q']); // q is the value of
what was selected

$options = array();
$map_path="C:\\ms4w\\Apache\htdocs\\img_browser\\";
$map_file="imgb_access.map";
$map = ms_newMapObj($map_path.$map_file);

switch($layername) {
   case 'landsat_4':
     $layernum = 3;
     $qstring = "Landsat";
     break;
   case 'ikonos':
     $layernum = 4;
     $qstring = "Ikonos";
     break;
   case 'hyperion':
     $layernum = 5;
     $qstring = "Hyperion";
     break;
   case 'mn_airphotos':
     $layernum = 6;
     $qstring = "MN DNR";
     break;
}

$layer = $map->getlayer($layernum);
$success = $layer->queryByAttributes($field, $qstring, MS_MULTIPLE);
$layer->open();

for ($i = 0; $i <= $layer->getnumresults();$i += 1) {
$resultx = $layer->getResult($i);

// THIS Does NOT give me what I'm after
print "<pre>";
print_r($resultx); // print_r($resultx);
print "</pre>";
}

++++++++++++++ END OF CODE ++++++++++++++++++
The last section (with print_r) shows me the result of my query but not 
in the form that I want.  I want to see the records in the dbf table of 
the shapefile that I have queried.  What am I doing wrong ?
