Thanks very much Pietro! I'm sure this will help many mapscript newbies!

Chris,
I don't read the reference, which doc?
I use mapscript 4.10 and, like you, function getShape don't exists.
to get attributes I do:
$obj_layer = $obj_map->getLayerByName("name_of_layer");
$obj_layer->queryByRect($a_obj_rect);
// or queryBYPoint, or queryByAttributes...
$obj_layer->open();
$i_numres = $obj_layer->getNumResults();
for ($i=0;$i<$i_numres;$i++) {
$resCache = $obj_layer->getResult($i);
$sh = $obj_layer->getShape(resCache->tileindex,$resCache->shapeindex);
print_r($sh->values);
}
$obj_layer->close();
I hope it is useful.
ciao

Thanks Pietro, though the reference did mention that the getShape method
was deprecated in favor of the getFeature one. This begs the question of
exactly how I would get the attributes associated with a particular shape.

Hi Christopher,
there is no mapscript function layerobj::getFeature(), maybe you need
the
layeroby::getShape().
(Effectively getFeature is a more exact name for this function: a
"shape"
don't have attributes, a "feature" is a shape with attributes)
take a look here:

*Hi all,
I'm having some trouble getting the getFeature method to work on a
layer
object. Here's the error I get:
Fatal error*: Call to undefined method ms_layer_obj::getFeature() in
*C:\ms4w\Apache\htdocs\test.php* on line *10
And the php code:
<?php
dl("php_mapscript.dll");
dl("php_dbase.dll");
dl("php_curl.dll");
$shape_id = 1;
$map = ms_newMapObj("c:\ms4w\apache\htdocs\es.map");
$this_layer = $map->getLayerByName('pn_points');
$attribute = $this_layer->getFeature(1, -1);
echo "ok";
?>
and the mapfile:
# This is our fifth map file

Any ideas? I'm totally stumped. I don't know if its the software
(mapserver
4.10, mapscript 4.10, php 5)or a mistake I've made that is eluding me.
