In PHP MapScript, the attribute (item) values are returned via a
shapeObj array property called values.

For instance, if your OGR data source contains a field called
"Population", then after a call to $shape = $layer->getShape() you can
access the Population attribute using:
   $shape->values["Population"]

Note that you can use print_r( $shape->values ) in PHP to dump the
content of the array and see what the attribute names are.
