Gert-Jan,

Yes, you have to use PHP's dBase module to access the attributes.  Also
important to note is that PHP dBase record numbers start at 1, but
MapScript's shape indexes start at 0, so when you read your DBase
record, you have to use:

  $rec = dbase_get_record_with_names($db, $result->shape+1);

See also the function GMapDumpQueryResults() in gmap75.php3 in the GMap
PHP/MapScript demo for a complete example of dumping attributes of
selected shapes.
